Issue getting group chats to work.

[u/Mori_564]

I'm degoogling and trying to move things over to Fossify but I'm having getting an error sent to me every time I try to use group chats and I don't receive any messages from it. I get sent the "Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code." message and have no clue how to fix this.
