It isn't, though I've personally never had the issues OP is experiencing. However, I do have the issue of the app signing me out after a few minutes of closing it from Active Frames. It will send push notifications for messages I receive after I close it from active frames for around 15 minutes, and I notice (when I check from a friend's account or something) that it has signed me out after that time.

Hopefully, they've included hub integration, and push notifications. I'm going to assume that they will, since they specifically went native instead of porting their Android app.
