Hi. My adventurers were sent an invite link with a broken error message. 
Any way to fix this? I reset the link as well..same issue. 

perhaps mobile devices vs. pc?

When you pasted the join link it may have inadvertently added a no-break space at the end, looks like this:

 

if so, that is what is breaking the link. Repaste the link and make sure that code isn’t being inserted.

Ill give this a try thank you.

If that doesn’t solve the problem try resetting the join link and send them the new one.
