Describe the bug
When trying to cancel or speed up a transaction on Trezor on Sepolia network, it's not possible due to message:

Unable to reproduce on Ethereum Mainnet, where speed up and cancel work.
Unable to reproduce for other hardware wallets like Keystone or Ledger, where cancel and speed up work on Sepolia
Update here: reproduced for regular accounts as well
