Comment list takes too long to load
Getting comment list to show in Acrobat DC takes way too much time. It's a drag. At least on Mac OS.

Hi All,
We have provided a registry protected fix, some users confirmed that this worked for them.
Could you please try this at your end as well and let us know your feedback?
Kindly make sure you are on the latest DC build(20.012.20043) and then follow the steps from the attached word file: “Steps.docx”.
Regards,
Arvind

Turning off fonts is not a fix, it’s a workaround. The software should be fixed to handle it. It doesn’t even require all the fonts for comments. There is no font selection. And even if it would, this should be moved to a background process, that works over time, with a fallback font, or at the very very least a loading bar. Just freezing the thing for 20 seconds is no way for a good software.
Also I don’t know if the RTF-ish support is even on purpose. If you copy formatted text, it sometimes stays in the format, but there is no option to remove or change it. It looks like this part of Acrobat is just poorly written.

"... fonts that you're not using..." I've seen that issue on machines that didn't have all that many fonts active. Anyway, that doesn't happen all at once.
However, good digital housekeeping will leave the most resources available, to mitigate software issues... -

turning fonts off that you're not using fixes this issue

I have exactly the same problem. It started a few months ago and has affected every PC in the company as well. I have waited up to three minutes for it to open. What an abortion! How much is this affecting the productivity of almost everyone on the planet I wonder? Adobe should be ashamed of themselves. If they can't fix the problem all they have to do is provide an update which is exactly the same as the previous version and leave at that until they can sort this ridiculous problem out. In fact I am going to use a third party reader and leave it at that and never leave myself at the ransom of Adobe again. I won't be acquiring any of their other products either. Their products are now unreliable, unproductive, overcomplicated and a waste of time. I am a very busy person and I don't have the time to wait 3 minutes every time I want to open a simple document.

Before the 2019 update this used to work file, but is torture to use every day since then.
I use the comments every single work day multiple times per day, and the lag is a tremendous waste of productivity. Please please fix this. -

totally agree with this. Click on the comments icon, instant colour-wheel. Go make myself a drink, have a poo, read War and Peace cover to cover and its still colour-wheeling. Its been like this now since the new Interface layout, which must be a at least a couple of years ago now. Why it's not been fixed yet, I do not know.

If they couldn't reproduce the problem, they must not have tried very hard.

Deactivating fonts on 'a daily basis' is an insane fix for this problem, which plagues me as well. It has nothing to do with any specific document, rather the poor implementation of the panel.

Go to whatever font manager app you use and turn off/disable all the fonts you don't use on a daily basis.

Could you please provide instructions to decrease active fonts

::ATTENTION::
I have a fix for this lag.
After a lot of troubleshooting, I found that it's the number of active fonts on your machine. Once I decreased all active fonts it immediately works with a click.

I've been having the same issue for years - 20 - 30 seconds to open comments pane.
The machine at the desk next to me with the exact same build opens the comments pane immediately

I think it's time you stopped asking us for sample PDF files, because it's clearly not related to any specific document. This happens on EVERY SINGLE DOCUMENT, regardless of whether it has zero or 1000 comments and regardless of what program created the original PDF. It's clearly an application and/or configuration problem. So if you can't reproduce the problem, it's because you've failed to reproduce your typical end user's hardware/installation/configuration environment somehow. If you start focusing on that, I'm sure we'd all be happy to provide any environment details that would help you troubleshoot.

slow slow slow with the beachball. so many complaints about this but seems like Acrobat is unaware. Are they even using their own product? i get this same behavior in 2 macs, a mac book pro 2014 and a new mac book pro 2017

Agreed. This is not only jobs with Comments.

It is not dependent on the file. Even in a file with no comments, the Comments panel takes 30 seconds to open.

As stated numerously, it doesn’t depend on the file.
But if you insist, here is a file: https://adobe.ly/2JNq6VTIt takes me 7.5 seconds to open the comment-pane.
Im on Version 2018.011.20040 and Build 18.11.20040.280397 -

As I've said before on this tread (approx 6 months ago), this is related to unpublished books which are confidential and which I therefore can't share. Sorry

Thanks everyone for reaching out to us. We tried to reproduce the issue at our end but were unable to do so.
Please provide the sample files on which the issue is reproducible. It will be of great help.
