While changing the color of the highlight of the selected text, the text gets to the centre of the screen.
e.g. I have highlighted something with a yellow color, but I need to change the color now. I tap on the highlighted text, options pop up, I change the color. As soon as I tap on different color, ‘the text’ which is elsewhere on the screen gets to the centre of the screen. Its really annoying, why can’t the the text remain where it is on the screen. Why it needs to get to the centr of the screen. This does not happen on the android app, why in the iOS app...? It needs to be fixed. You don’t want the page slide up and down to get the text to the centre of the screen, It really disturbs while studying.

I have a problem with a PDF I’ve imported from Telegram on my iPad Pro 12.9" 2015 (even if I don’t remember whether I copied it or I just opened with Adobe or even if I copied it to Notability and then I sent it to Adobe).
In Adobe the file has changed name in "Telegram-cloud-document-4-...[many numbers].pdf” and is only 45 bytes.
Every operation done with this file fails with unknown error so that it is in the main page when I open the app and so it is upsetting to see it every time... I would like to eliminate it or at least to remove it from the main page.
I guess that Adobe created a node in its graph but without the associated file, but I can’t understand why.
Thank you
PS: I had iOS 11 when this trouble have begun and now I have iOS 12

For files in Dropbox, there is an icon with a cloud and an arrow pointing downwards, which allows me to download a offline copy that I can open later. This feature is similar to that of the iOS built-in “Files” app. However, for certain large pdf files, the Acrobat app sometimes re-displays the cloud icon next to the file’s name after certain period of time, requiring users to download it again (but being large is exactly why I need an offline copy!). The built-in “Files” app never does that; it seems to be keeping downloaded files for much longer time, in fact it never deleted one on my end.
Because of this, I am currently using “Files” app for keeping offline copies and “share” it to Acrobat app every time. I hope Acrobat retains offline copies for longer time as “Files” app does so that I can solely rely on Acrobat app!
