[Bug] Null value set to PhotoUrl is not saved on Android devices

[georgemarkosian]

Description

Our app has a user avatar feature that allows users to delete their avatars. It's done through setting a null value to PhotoUrl and calling UpdateUserProfileAsync method. This works well on iOS and in Unity Editor, but on Android devices the task completes fine but the change is not applied.

Reproducing the issue

0. Use Android device
1. Call UpdateUserProfileAsync with user profile with valid Uri in PhotoUrl
2. Call UpdateUserProfileAsync with the user profile with PhotoUrl set to null
3. PhotoUrl doesn't change and remains the same as set on step 1

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reaching out, @georgemarkosian. I was able to reproduce the same behavior. I'll go ahead and notify our engineering team.
