How to free up storage taken by the “On My iPad” app?

I have a 6th generation iPad, iPadOS 13.5

I have used an app called “On My iPad” that came preinstalled to this iPad to copy files to this iPad (like PDFs, movies, etc.). Eventually, I deleted all the files that I have copied (at least this is what I think I have done).

The problem is that there is still a lot of storage taken by something in this “On My iPad”. Has it not completely deleted the files? How to clean up the storage?

Please see the screenshots.

You can see that there are zero items showing when I open the “On My iPad” app. There are three folders Downloads, Keynote, Pages, and they are all empty.

iPad Storage

When I look at the overall iPad storage I see that there is about 1GB taken by the “On My iPad”.
Also, there is a discrepancy in the reported available space. The “On My iPad” above shows that 20.31 GB available. The iPad Storage reports 14.3 of 32 GB used, i.e. only 17.7 GB is available.

Documents and Data

When I tap on the “On My iPad” to see the details, I see that “Documents and Data” take 1 GB.

When I tap further on Recommendations, there is nothing there. When I had some files, they were showing here. I have deleted all I could. Apparently, something is still sitting somewhere.

I have seen advice to delete an application and reinstall it back to reclaim the storage taken by the “Documents and Data” and I have done this trick successfully with the Keynote application. But there is no option to delete the “On My iPad” application and there is no such application in the App Store, so this method can’t be used here.

Any ideas?

Why won’t my iPad backup?

I always get notifications that my iPad “hasn’t been backed up in X weeks. Backups occur when the iPad is locked, connected to WiFi and charging.” I feel that this must occur all the time, but the iPad still does not back up. Is there a certain amount of time the iPad must be in that state before a backup is completed, or something?

Why is opening a link in a new tab on iPad Safari suddenly so finicky?

Out of nowhere – unless it was a recent small software update – I have noticed that whether or not Safari allows me to open a link in a new tab, by holding CMD while pressing it or holding the link and selecting the option
“Open in New Tab” – fluctuates a lot and seemingly randomly. Very often the feature is suddenly unavailable and then it comes back. Is this a new glitch or something?

iPad 2 screen does not respond in the top half

I have an iPad 2 that I got for free and that I will repair (digitizer) and give to my nephew. Before I fixed the problem, I figured out what to do about it and found in portrait mode that half of the screen couldn't be clicked or touched. Do I need a different part or just the digitizer? I plan to fix this no matter what happens. Please don't just scold how useless iPad 2s are. Thanks in advance!
