Hello,
Adobe Reader is the only PDF reader that cannot open properly some kind of PDFs generated by the LaTeXiT software (I am the developer BTW).
Those PDFs have a particularity : some metadata is hidden by using microscopic (1e-6) font size with transparent text.
The PDF is generated through Apple's Quartz technology and standard drawing commands, using the standard Courier font.
No PDF standard seems violated, but Adobe Reader complains about TrimBox problems (while all other PDF readers just work).
Is there any reason/workaround ?
It seems to be a bug in Adobe Reader.
Here is attached an example.

So as of 19.09.00 and 19.09.01, when in Dropbox on iOS (I am using an iPhone XS max on 12.1.2), when you open a pdf and select to edit and open in adobe acrobat, acrobat cannot open the pdf and gives an unknown error.

Windows app has the option to sign a PDF with Digital Certificate or Digital Signature(once you have your own Digital Certificate installed in the computer), but iPad and iPhone don't.

It would be great if you could use the pinch to zoom feature to zoom out further than the current setting on iOS. Right now, it will fit to screen width and this can be too big when the tablet is in landscape mode.

Since I exclusively use my iPad for study purposes, there are lots of pdf's I have to work on at the same time. Ability to open multiple pdf's in tabs at the same time would be very beneficial for me rather than having to go back and open another document.
The feature is available in windows so why not make it available in ios too. :)

Few more colors in comment option for highlighting, underlining, etc will be great. Definitely missing the orange color.

I want to cancel my Premium Acrobat subscription

Cannot resize PDF files.

After actualization the new app keeps deleting/not saving the coments, the highlights, etc., all the modifictions I do to the pdfs. Why?! It is extremely frustrating, as I work with Academic texts in my PhD research, and I lose every single note I add. This never happened in the ancient app, which was very fine.

I think it would really useful if you could open OneDrive and other cloud services (box, google drive etc)

It is taking hours for a 3 page PDF to combine the individual PDFs. HELP!!!

When viewing PDFs in Reader, it would be ideal to have the option to rename the file without being required to exit the file and view the files list and go through the process of renaming the file from there.

Make accounts for business

It is urgent to get access to my full features of my already paid subscription

We need a way to password protect PDFs from mobile devices.

I think this translation is improper. (Define→定義する)
“定義” is a better translation than ”定義する” because ”定義する” means to define a word by the user.

This app is Acrobat for iOS version 20.06.00 (20200615.160636)

When using an Apple Pencil to add a signature, palm input on the writing field creates a line from palm to the tip of the Pencil. Very annoying when using the stylus as you have to write with your hand hovering in the air, not resting naturally.

I want to be able to directly transfer pdf files from other cloud providers directly to Adobe Document Cloud. This should be available only on the Desktop. For example, transferring from OneDrive or from iCloud the PDF files located in a target directory with an option to import all PDF files from child directories.
