Have completed level 1500 with 3***, not moving to next level on windows 10 mobile, yet will and has on Microsoft surface, accounts are linked so what is going on?
Aha, you're playing as a guest on the mobile device, that is why I could not see any mobile connected to the User ID.
So this is a Windows device correct? Could you do me a favor and go to Microsoft Store from the device, search for the game and send a screenshot of the system requirements?
I will also need the game app version you have installed.
