I just join and having problems inviting friends. I was testing it at home. Signing up as Master is not a problem. I bring my 2nd compter to another room to sign in with the link and it came out as Master. not as guest. What is the problem?
This would be the normal behaviour if you are signed into your Watch2Gether account on both computers. Try to sign out before testing with the second computer or try it with an incognito window.
To test the system, after I sign in as master. how can I sign in as guest or friend on another computer and not as master? I sign with the invite friend link but it came out as master.
Are you signed into your Watch2Gether account on the other computer?
