I can provide screenshots via email. Suddenly, although I've changed nothing, I add a sticky note and it has someone else's name who had never commented on a PDF ever, and is not associated with my account!

Myself and a coworker cannot open a PDF with sharing/commenting capabilities. Acrobat DC Pro will open, but once I select a file, the program closes. I have uninstalled and reinstalled the program. The PDF will open in Preview.

The arrow in the comment section will not change color... It seems to be locked, but when i click on Properties the Locked box is uncheck. The only way to change the color is to make it a default, every time.

Text call out tool issue . After commenting on a document , the color of the call out box is changes to blue and this property made "default" through " make current property default " option. This change is valid as long as acrobat pro application remains open . When the application is restarted , the text call out box reverts back to the original properties i.e. white in color . This problem comes for the text call out tool only and other drawings markups retain their set properties even after restarting the application.

My problem is that when I try to print comment sticky notes on a parallel page, after the first day's work, when I start up the next day, I can edit with sticky notes, but cannot make them open on the parallel page. The first day's sticky notes are there nicely, but the second day's will not open on the parallel page once entered on the main text page.

When one clicks the highlight icon or comment icon (accidentally or on purpose) one is committed to doing more highlighting or commenting. The best one can do right now is click some other icon. One wants to go back to just selecting text. (The same should hold for other icons.)

When I sort comments by author, then try to select all comments by one of those authors, I am unable to select all of them, only a portion. It looks like it grabs them all, but if I change the properties, then look at the sort again, it shows only a portion changed and the others still have the old properties.

Text Call Out from Comment Section incorrectly moves with arrow keys. While selected this tool moves down/left by all keys only. All other comment tools allow you to move items around / position by selecting the item and using the arrow keys while this one programmed different. Only solution is use the pick tool to grab and move with mouse.

when importing a custom png stamp that has clear background, it now presents as black and opaque instead of clear. This functionality used to work, and it now is broken. This appears to be effective for PNG or TIFF files.

I can't delete or modify them.
