Electronic bundles created by scanning a physical bundle with double- & single-sided documents tend to have a high proportion of blank pages because the person doing the copying generally finds it easier to scan the whole bundle double sided.
The blank pages increase the file size and make working on the bundles very annoying.
Currently the only option is manually removing the blank pages, one at a time and although it solves the problem in the long run it is an immensely irritating chore itself.
Adobe support on Twitter thought they had a fix using the 'Page is empty' function in Preflight but it doesn't work because a scanned blank page is not detected as empty. It would be really useful to have a fix that could detect scanned blank pages as well as coping with the occasional small mark such as a hole punch hole or a scanner glass scratch/smear.
At the moment with remote working as a barrister I'm getting typically about 10% of blank pages routinely and up to almost 50% from time to time in 200 to 1,000 pages of a brief or set of instructions.
I can't send an example because all those I have contain legally sensitive material, I'm afraid.
A feature that identifies these blank pages and facilitates their removal would be immensely helpful.
There would need to be a 3-step 'Identify. Review. Remove.' approach because there will be some pages that have almost nothing on deliberately and it would be dangerous if one simply hit a button to "Remove all blank pages". That would be too blunt a tool.
There would definitely be a demand for such a tool in my field as the courts in England & Wales have gone on to double sided bundles as of the 6th April - https://www.civillitigationbrief.com/2019/04/02/the-rules-they-are-a-changing-new-rules-on-bundles-from-the-6th-april-2019/. Adobe support on Twitter suggested I put the idea to you.

The font list on Mac Os Acrobat is in the standard font- see screenshot (usually each font name is shown in its style so you understand what it looks like more or less).
On Acrobat on Mac Os in order to see what font looks like you need to apply it to the text in the document - so you literally need to apply 100 fonts to see what they are when looking for the right one.
In short - there is no preview samples of fonts on the list like there is on Acrobat on Windows. I had to cancel my subscription on Mac because of that and i am sure i am not alone.
I spoke to your customer support and they confirmed that it is so and it's not a bug. If possible - let me know when it's fixed so i could subscribe again.
thank you.

I've just started using Adobe Acrobat DC, continuous release. I noticed when editing a document, if I select the drop down list of fonts, all of them show the exact same font type in the list. This is really unhelpful, because I don't know what any will look like.

This leaves me with two options. One, choose a font, see what it looks like, and keep it; or if I don't like it go back, click the drop down list, and re-scroll all the way through to find the next font in line and try that one. If I don't like it, repeat, repeat, repeat.

Or I can look up online and type each font I'm interested in one by one, until I see one I like. Both INCREDIBLY time-consuming and tedious.

How about like MS Word, show what the fonts look like by showing each name in the format of that very font. I think it's a great feature. In fact, it's such a kind of obvious feature, I'm wondering if there's an option in there to turn that on or off. I can't find it in a Google search, anywhere right now.

There needs to be a simple way to convert text to path. (The utility of this is begin able to use parts of the pdf file in illustrator without having the fonts.) Googling this shows there is demand for the feature. Currently the feature sort of exists in the "flatten transparency" settings, but it does not work correctly if there is no transparent feature in the pdf. The workaround is to add a watermark or other transparent object, THEN edit the flatten settings. Silly workaround for a common enough need. I'd call this a bug, since the flatten options clearly include a "convert text to path" option, it just doesn't work unless there is transparency in the pdf.

Mac OS X 10.13.6
Acrobat Pro DC – Version 2021.001.20138

Inserting a text watermark using the Helvetica Neue font enters a series of boxes instead of the text. All weights and slopes affected except, bizarrely, the ‘Thin’ weight.

Inserting text using the Helvetica Font produces the error message “The font ‘Helvetica,Xxxx’ contains an invalid encoding. Some characters may not display correctly”. This error message appears on saving the PDF and every time it is opened in Acrobat Reader DC.

Both fonts are system fonts and work satisfactorily in all applications (e.g. InDesign, Word) including Acrobat Pro DC, but not as a watermark. The fonts check-out as undamaged, and are not in conflict with any other fonts.

This bug is duplicated on more than one installation of Acrobat Pro DC on separate Macs.

It looks suspiciously like a bug.
