Sooo, I don't know where to provide feedback, so I'm providing it here:
Today I received an update to Viber, no jump in versioning so far, but I don't care, because notifications started working finally!
Well...at least sort of...
Now I am receiving updates on the live tile counter and thus on the lock screen.. So at least I don't have to wake up the phone to see if a new message has arrived.
The problem is, that when I receive e.g. 3 messages, the in-app counter shows "3".. But the live tile - and thus the lock screen - most of the time displays "99" - which seems to be the maximum count.
Closing the app does not fix this. Sometimes on a new message the counter shows the correct number of new messages, just to start displaying "99" on the next received one..
Well, but hey, at least the live tile and the lock screen now do show SOMETHING at all
EDIT:
Restarting the phone did not fix the issue either - live tile and lock screen are still displaying 99 new messages, although there are no new messages in the app itself. Let's check the behavior after I have received a real new message..
