Push notifications for microsoft authenticator app for ios gets permanently disabled

Question

after reset of settings in iOS by clicking Settings > General > Transfer or Reset Phone > Reset, the push notifications get disabled for Microsoft authenticator apps, which does not get reenabled.
Subsequently notifications does not get reactivated even after opening the Microsoft authenticator, which does not show prompt for allowing push notifications as it did upon first install of the app.

This issue with Authenticator app not registering for APNS occurs only when the iOS Settings are reset and the app is launched subsequently. It is resolved if app is subsequently uninstalled and re-installed. Authenticator app also registers correctly with APNS when the app is installed afresh. 

Other apps like YouTube and Facebook don’t face this problem. They register with APNS whenever they are launched subsequently to reset of iOS Settings. 

So my request is to resolve the authenticator app coding which ensures that it registers with APNS when the App is launched even after iOS settings are reset. 

The app too don't show up at all in list on ios settings > Notifications, till the app is uninstalled and reinstalled.
This issue does not occur with other apps like YouTube or Facebook. 
Please rectify this bug in Microsoft authenticator app.
