Archived messages return to the inbox if QKSMS is not the default application.
Alternate steps where QKSMS is already used as the default:
Previously archived conversations should remain archived, but instead they are all visible in the inbox list and the archived list remains empty.
Tested on current latest F-Droid build, 3.1.1.
Not ready to make it my daily driver for SMS just yet, but glad to hear it's back in development!
Hmm, I'm not able to reproduce this on my own device on 3.1.3. I'll do some more testing and see what I find
Testing with a Nextbit Robin on Android 7.1.1 with a few thousand messages on some contacts. Also occurs for me if QKSMS is swiped away / force closed in settings, but not when pushed to background.
Checked against F-Droid version 3.1.3 and Google Play version 3.1.3; occurs on both for me. Wiped application data between a few runs to be completely sure, too.
It also unarchived messages for me with the following steps:
I've changed some things with how the message syncing is done after the app is set as the default SMS app, in version 3.2. I'll be releasing it in the next couple days - once it's out perhaps you can try it out and let me know if does anything for you with respect to this issue
F-Droid hasn't picked up the new version yet, but it does seem to be fixed in 3.2.
Thanks!
