I created a Nintendo Account in order to play in two linked devices, but once I tried to enter in the account I just created with the second device, the system says: “The Nintendo Account you tried to link is already linked to another game account”. What does this means?
EDIT Issue solved: 1. delete the app from the second device (the one where the sync problem message appeared) 2. download SMR again on that device 3. Sign in with the account already created on the first device 4. Apps on both devices are now synced.
