I panicked because I thought I lost my Bitcoin Cash, Ethereum, and Litecoin. Turns out that Trezor Suite said “This hidden wallet is empty” just because I didn’t have BTC in the wallet. After logging into the “empty” wallet and re-enabling the other coins, the money appeared.
I suggest to have the message say “This hidden wallet has no Bitcoin in it” instead. Even better would be to let us select coins before logging in.
(P.S. Add Nano support.)
