Nextcloud V19.1 unstable

I am new on Nextcloud. And new on Ubuntu Linux.
A friend installed all. But after he updated from Version 18 to 19, he has no more time.

But on clients on Desktop and Android devices, there are so problems in speed.

I was not able to fix in case of my knowledge.

Please can anyone help me out?

  1. Cache seems to be wrong. Or just a wrong warning?
  2. Automatic upload of images in App blocks the Mobikd device and crashes. Can be solved by cache on server?

I am willing to pay if you can fix it by Remote Desktop. Or leave a comment here, I will try my best to execute your recommandations.

SSH is available.

App Upload never stops, and freezes App.
