@ij@nerdculture.de I upgraded to that version and the only problem I had was, I had to adjust the database entries. However, I have found that upgrading the apps before I upgrade the Nextcloud version solves the problems you just outlined. I too have practically all the apps activated in Nextcloud and I did have those problems too. However, if you upgrade your apps regularly before the version upgrade, you may be less frustrated. I've been running the same instance of Nextcloud for almost three years and I've kept to this system and it seems to work. You're welcome to try it to see if it works for you as well. Good luck.
