Ok thanks I will follow your instructions guys.
My seed is correct 100%. No 2fa. I can't really import my old wallet. And when Im typing my bitcoin address instead that's the time NEXT button will be enabled.
In that case you are probably clicking the wrong Option, should be something like New Wallet - Restore from recovery seed or something similar. If you are clicking from "Watch address" or something similar, it will not accept the seed at all. Is it possible that you could send a screenshot of the window where you enter the seed? Of course without the seed or it censored.
