Brave developers are very confused, about what they say and moderators here too. I am still suffering with my previous issues, to resolve them they gave me some repeated instructions to perform but nothing came out, and they now don’t even afford to respond.
I was also facing issue with maximum device limit reached for wallet, but I filled a form to request to unlink my wallet from inactive one, so I could get a slot to link the active one, and it worked. Also, they stated from March 1 onwards there would be no limitation, but it is still there.
If you want to submit request to unlink then follow this link
