Yes I’m having major problems with it. I’ve actually had to stop using it until they figure out and fix whatever this issue is. I am not getting any notifications at all and have to manually go into the app to see if I have any new emails. There must be some type of issue with their servers because it was working great on iOS 13 and then all of a sudden it stopped working.
Make sure to email them and tell them about this issue. The more people actively reporting on it the better.Me too! Notifications are nonexistent on my iPhone 11. What is interesting is that it appears to be working on my wife’s 8+ with iOS 13.
