I sent invitations to my family members. They receive the email, click on Accept invitation, but I does not work. I enter the code in the exchange and it says that it is invalid. Can someone help me? Thx
Apologies for the late reply, but maybe I can still help :)
Have you tried to use an incognito tab, clear the cookies of your browser and use another browser or device?
When this doesn't work, you should try to use another internet connection (e.g. cellular data instead of WiFi).
Have a nice day!
