Last time I checked, Nextcloud Talk android app simply refuse to implement any sort of pull system. If one’s using a google-less phone one needs to set up a push system on top (I’ve never managed to get the NC push system to work properly). There’s even a separate “Nextcloud Notification checker” app on F-Droid to remedy the problem. It’s all a bit silly.

Same, it’s pretty nice.

to be sure that I (the server admin) cannot see the content of the files

temporarily upload files to my server and then serve them to users after

Heh.

I recently checked up on the status of the built in E2EE in NC when deciding what sort of encryption I wanted for data at rest on a self-hosted system. People are still complaining about data loss and horrible bugs. I’ve been burned before and stay well away from that half-baked implementation. I just use Cryptomator instead.

On the other hand NC supports AI implementation, there’s machine learning that sets EVERY SINGLE MAIL to important in the mail app and the ActivitiyPub based Nextcloud Social have almost worked for many years so that’s nice.
