Summary:
I am unable to receive invitations.

Steps To Reproduce: (Two devices and two Microsoft accounts required, referred to as 1 and 2)
1. Open a world on 1 and set it to "Invite Only"
2. Pause the world and invite 2

Observed Results:
The invitation does not arrive at 2's device, and so, 2 cannot join 1's world

Expected Results:
The invitation does arrive, and so, 2 can join.

Affected Platforms (keep updated):

Android
Switch
Windows 10

Original Description:
Everytime someone sends me an invite to their world, not realms, I do not receive the invite. No notification. I tried messing with my XBL settings to no prevail. When I send invites, they receive. This has been happening since 1.13.1? I just want to be able to receive an invite again. I do not know if it is replicable as it happened out of the blue.
