I have, but it's gone without a response for awhile. I was hoping to see if community support would help fix the issue before. Was worth a shot, at least.

All of those have been set to open and public, and haven't changed. Still not sure what is going on.

I have that disabled.

What settings can change privacy?

I'm having the same issue. No matter even if we are in the same block, I cannot join or start parties. I get the same issue every time, "You can't invite that player to your party at this time."
