Not getting the updated user profile details such as Phone number

[pavanajain]

I am using Firebase Phone Authentication in my Flutter app (for Android and iOS).
Using same Phone number I have logged into my account in two of my devices.
When I update phone number on one device I expect the updated phone number should get a real time update on device2, on which I have subscribed to userChanges() method. But device2 still shows the old phone number.

I have also tried to get updated user profile phone number in device2 using reload() method, but as soon as I call reload() I am being signed out of Firebase account.
Kindly help!
