Creating NFT using Ledger and My Algo Wallet

It errored out in the end and referenced a hardware limitation with the Ledger…I’m blown away that I can’t use my Ledger to fund my creation. Am I doing something wrong? A Google search isn’t very helpful

Asset creation are asset configuration transactions.
So these are supported.
However, the Ledger Nano has a limit on the URL size.
It may be possible this is creating the issue you are seeing.
