Which notification did you test with?

[sanek8686]

Nextcloud Talk v8.0.2
Send message to user, call user. No pop up notificashion

[nickvergessen]

This was actually fixed with #496 which is part of 17.0.3 already 🤔

[sanek8686]

I rechecked. After change language no notification in android application.
Nextcloud 17.0.3

I can confirm this issue. My NC is 17.0.3.1. After changing language to Russian the following errors appear in log:

Also after this error the public key is erased from the "oc_notifications_pushtokens" table.

[nickvergessen]

Arg, okay I found the actual issue now. json encoding some characters does not only double them in length, but actually makes them 6 chars (\u1234).
I fixed that with https://github.com/nextcloud/notifications/pull/575/files and tested it with a russian account on my phone and it does work now and exploded before.

Feel free to test and verify this on your instances
NOTE: as per #563 (comment) push tokens are deleted on errors, so you need to remove the account from the talk app and create it newly.

[alexlo0]

Excellent! Now it works as expected. I've double checked with a user from scratch in Russian and another user at first in English and then changed to Russian. No errors, no broken certs. Thank you, good job!
