Versa 3 and Sense (SDK-5) not working when testing from GAM but works when sideloading app

[FrostFrozen]

We completed the development of our Fitbit sdk app for SDK-5 and SDK-4.2 and as suggested in the community previously that we should have the same appUUID. 

We did exactly as said. 

When testing it with iOS we got all the file transfer working correctly for SDK4.2 and iOS version 14.1 but when testing it with iOS 14.4 and SDK 5 sdk app the file transfer doesn't work. 

The code for File transfer and everything is same. 

Can someone guide us here? 

Note: Both versions work well on Android and file transfer is successful.

This is a long-shot, but look for any evidence of the companion app being automatically closed after 15 seconds. Debug output in the console might indicate; or see if it works for the first 15 seconds of being started and not thereafter.

This is just a hunch, and hopefully a wrong one.

We debugged the same code with Versa 3 and iOS 14.4 and file transfer is going through and things are working fine, but when we publish the app privately and share the link it seems to stop working.
