I was trying to get a Cosmere game going with some friends of mine. I had 5 people who were meant to join in, but three had issues getting in the group.
Two of them were able to get into Demiplane, but it sent the request to join twice and neither would let me accept them into the group. The only option was to send an invite.
The other friend who had issues joining has a Demiplane account that he could not log into. He would put in his login information and it would say the account is not found and send him to create an account using that information. Then when he would try making the account, it would say that username/email is in use. We tried resetting the password, and it still gave the same errors.
For the friend who is unable to sign into his account please ask him to submit a support ticket via our help center.
For the other friends let me have you start by trying to invite them again in a different web browser, make sure they’ve accepted the invites as well. We’ll see if that fixes the issue. If not, let me know and I’ll dig in a little deeper and see if I can track down what’s going on here.
