Yest it's signed with trezor but can't be verified with an other app or service (like Bitcoinsummoner said)
Try signing from a legacy address (starting with a 1)? If you ever need to verify ownership, it's convenient if it can be verified by people who don't own certain hardware.
Thanks, with legacy address it's ok
