In game guild chat issues

Platform, device version and operating system:
Xbox One

What you were expecting to happen, and what actually happened:
Some members of our guild are unable to see each other in our guild chat. Some can see everyone.

How often does this happen? When did it begin happening?
It started with the new update.

There are at least 4 members who can’t see each other in guild chat. Is there a way to correct this? Has anyone else ever experienced this?

Is this a known issue and nothing can be currently done about it?

Is this something that I should contact 505 about, in order to get it resolved?

Did you submit a ticket about it? If not, try that.
