Fitbit version 2.78 was supposed to fix Android 9 (Pie) issue with 'unknown caller' on Versa call notifications.
New permission for call logs is allowed
However, now not getting any call notifications and also 'Send a Test Call Notification' doesn't work (previously working before ver. 2.78)
I have tried all troubleshooting steps including;
reset tracker
re-enabled notifications
reset bluetooth
removed and reinstated Versa as new device in the app
factory reset of Versa
