(Looks like Yoroi is no longer an option there. Go here: Yoroi - Light Wallet for Cardano and click “Contact us” in the bottom then “Contact us” again in the chatbox, there you’ll get a form to enter).
They need to know that this is affecting multiple users. I got a quick response from support but it was only a suggestion of errors that could be on my end (wrong Trezor, wrong passphrase, etc).
Then let us know if they give you a solution.
