iCloud Drive favorites have been disappearing frequently from the sidebar in the Files app on iPad and iPhone. After a while, they reappear, then they disappear again. When this happens, tag items are also not shown (wheres the tags themselves are shown in the sidebar).
For me, this is a major issue since iPadOS does not have symlinks that I could use to quickly access folders and files. Without favorites and tags, I have to navigate through the whole hierarchy for every file that I need. This is quite cumbersome.
It seems that I am not the only person who is affected by this. People have reported related issues since February 2018. Apple has not fixed it in five years:

The following list shows things I tried. So far, nothing helped permanently.
I have sent multiple bug reports to Apple.
I tried to unfavorite folders and re-favorite them, but I cannot even unfavorite folders on my iPad when this happens. — No fix.
I waited: sometimes the favorites re-appeared after some time. — Only temporary fix.
I updated iPadOS and iOS. The problem still exists after updating to iPadOS 16.3. — No fix.
I dragged the favorite folders to the sidebar. — Only temporary fix.
I added tags to the favorite folders. That made them re-appear in the sidebar — Only temporary fix.
I moved the favorite folders into a new folder. — Only temporary fix.
I deleted all my iCloud Drive data, stopped syncing iCloud Drive on all my devices, the started syncing again and copied the data back into iCloud Drive. — Only temporary fix.
I removed third-party apps from my devices that integrated with the Files app: Cryptomator 2 and OneDrive. — Did not fix it.
I deactivated MATLAB under locations in the sidebar — Did not fix it.
I temporarily signed out of iCloud on iPhone, iPad and my MacBook — Did not fix it.
Uninstalled VPN profile and app and did a reset of network settings — Did not fix it.
I contacted Apple support and sent them iCloud Drive log files. My account is now in escalation mode so that developers can anyalyze the problem better —- So far, the problem still occurs.
It seems that only a few users experience this. So, what is different on the iPads of those users in contrast to the majority of users? I’m still looking for a better understanding why this happens and how the problem can be permanently solved.
