do app updates need verification. ive verified the original app recently but it tells me there is a July update to do
If you want to be sure you can do verification each time, or you can just use Trezor web version in your browser that is automatically updated to the latest version.
This even works in Tor browser and they have dedicated onion address, for better privacy.
I will post the link bellow, but don't trust me and verify for yourself:
