Has anyone at Apple acknowledged this intermittent iOS device registration issue when using WiFi? I have been having this problem for weeks using Azure Push Notifications. Microsoft brushed it off telling us "It is an Apple issue".

Well, I do not see installing an iOS app using Cellular Data instead of Wifi that makes use of Push Notifications as a solution. At least Microsoft has acknowledged this iOS defect in their Xamarin Push Notification sample code... https://github.com/xamarin/xamarin-forms-samples/commit/b4c1b55f9ecbdeced089c5fe1ad880e6c453eac6 _"On iOS 13 and greater, you may experience intermittent device registration issues if your app is running over a wireless network, rather than a cellular network. For more information, and a workaround, see iOS-13 Unable to receive Device Token - https://developer.apple.com/forums/thread/128172 on developer.apple.com."_ We have lost endless hours dealing with this issue. I wonder why Xamarin Android does not have this issue using the same Wifi and/or Cellular tower connection. Anyone know?

Apple? Absent again.
