I've tried to press the mark everything as read button every time I've read all the messages and it has improved slightly but the problem still persists.
In our setup we've activated "User Read Tracking" but it doesn't seem to work as I would have thought. Is it something I'm missing or is this feature not working perfectly, what issues are known about this feature?
I can see that I have rows getting inserted/deleted into the database when I post/read threads but it still doesnt' sync between devices. I can have my computer aside my phone and they show different results. Is this working for you?
I'm on version: 2.2.3
Yes that problem is a known issue. I will fix this issue with the next release.
I created an entry in the github issue tracker
