I inserted my trezor today and opened the app. It immediately showed all my wallet information. There was a message at the top about updating firmware. I clicked that then backed out of the update before I started it so I could verify I had the phrase backed up. I unplugged the trezor closed the app, then restarted the app and plugged in the trezor. The app asked if I had previously used this trezor, i said yes and was prompted for the pin. When logged in it showed no wallet info
