Updated Trezor HW wallet to latest version Updated to gui-win-x64-v0.18.1.0 Running local node

No issues receiving xmr, but receiving above error message when trying to send.

Any ideas on how to fix this?

Answer 1

The current version of the firmware contains a bug that disallows users to send to an integrated address from their Trezor Monero wallet. Please see other reports here:

Fortunately, ph4r05 has fixed the issue and created a pull request:

I am currently not aware of any ETA for the new firmware release, but I'd expect for it to be released shortly.
