Got to say I have not had time to look into this for private reasons, and so I am also on 4.4. The observations so far state an issue with SailfishSecrets. Maybe something changed there between 4.4 and 4.5. In know there are some other apps also making use of it (e.g. Storeman). Maybe there are already some findings. In the moment i am totally out of sync and have to do some tests and research, as much as time allows.
Latest Nextcloud Talk client did not work with more the one account .
After an update of the client (and SailfishOS) i tried to use the Talk client again - i didn’t use it for a few month .
But i did not see my old chats and so i delete both account i have created earlier (and witch worked before).
Setting up the first account and looking for the chats i see the old chats. But when i setup the second account (with a different user and server) the chats of the first account vanish and the chats of the second are also not visible.
I tried it multiple times with different setup order but the result is always the same. The chats of the first account are visible but setting up the second all vanish .
Did anyone have second accounts working on SailfishOS 4.5.0.19 and the latest Nextclound talk client?
