Can’t transfer funds.

I have a Trezor wallet linked to mangofarmassets and have some RVNs over it. I want to transfer them, so I connect my Trezor, sign in to MangoFarmAssets and send RVNs to the address, transaction gets signed but it gets stuck on "broadcasting transaction". I can't access my funds tho my Trezor works with other coins. Can anyone help me?
