Also you should be able to calcel an unconfirmed bitcoin transaction on Trezor Suite:
The "Speed up" and "Cancel" buttons can be found below the pending transaction in the "Activity" tab. Remember, you need to pay a fee (gas) to be able to speed up or cancel a transaction.
What does this mean?

Do I always have at least 10 minutes, 3 hours or 1 day to cancel the transaction?
