i also opened this thread about xmpp problems on my xperia device with the latest os version.
(still not sure that my pinephone os version is the latest. today i have the issue that jolla store tries to update some software and fails).
and there i do have ‘presence’ section in ‘settings’, and i do have jabber connection, and i receive messages, and i can reply, but all the contacts look offline. i tried your script on xperia device but it did not help to fix those, other issues.
again, thank you for the script. i rebooted pinephone, and i see my contacts’ status in the addressbook and contacts app. before the contacts app was not populated, and i was not able to use jabber at all, and i had no presence section in settings.
