modifications lost after a delay of inactivity

[tykayn]

Describe the bug
after some time without activity (minutes or hours), the user is logged out, be we can still fill cards and move them to other columns. Nothing notifies us our modifications will not be taken, the app acts like everything is ok but when we reload the page we are still at the previous state. this is really annoying.

To Reproduce
Steps to reproduce the behavior:like described, could take lots of minutes to see the bug.

Expected behavior
I expect the app to show a thing saying we are logged out, or anything blocking us from interacting with the cards if modifications will not be taken.
or something to automatically re

That is an issue with Nextcloud 13 since after some timeout the CSRF token is becoming invalid. There is nothing we can do about that in deck, but with Nextcloud 14 the token is updating in the background so the issue should be fixed there.
