Hey I'm Daniel,

I'm not exactly sure of the cause of the problem but that use to occur when I switch from being a part of a party on my xbox to my phone and laptop. I'm not sure if you did that before but that can be a cause of the problem so worry not more or less it should
be back to normal soon.
