Clients weird behaviour after upgrade

[JonDoe]

Hi there everyone

I'm running jellyfin on omv-compose (docker) and just did an upgrade from omv6 to omv7
All seemed to work fine but i decided to update also the container so i did a dow, pull, up.
Now this has worked ok in the past but now i'm faced with weird behavior.

I have several accounts for me, wife, older kids and one for the smaller ones.
I am the only one with admin rights.

Clients are running on pc win10, android phones and android tv

After pull, up, all clients except mine (both desktop and android phone) stopped working.
After a few restarts (client and server), my desktop client seemed to work but was extremely slow to react and most options in the user menu were not working.
So i did a log out and log in and now i only have a blank black page with nothing on it.

On my phone i only get a black screen with Jellyfin logo.

All other clients work ok except most options in the user menu don't do anything.

My wife's phone seems to work ok, menus and all, but i don't think i have updated the android client to latest (woman's phone - a mess).

I looked at he server logs but did not see anything unusual.

Please help me debug this as it's gonna drive me nuts.
