This is not something that i had noticed beforehand, although a friend has recently bought an S10e and noticed that the facebook app does not update with an App Icon count for notifications.
I have checked my S10+ and it is the same, although this doesn't bother me so much that Facebook is not notifying me with constant updates. However for my friend she finds it frustrating that she cannot see an Icon badge count on the facebook app. Most other apps seem to be fine with these icon badges including email / ebay etc.
Any suggestions for a fix ? Do others have the same issue for these app icon counters with FB ?
In the notification settings for the facebook app, they have all been enabled in 'silent' with App Icon Badge enabled.
