poorstudent Oops yeah there's one more issue, we set Fortmatic wallet to run via our sidechain whenever you're in the app. Long story short, the values you're seeing are from our separate sidechain (https://scan.morpher.com/) ie trading account rather than global crypto account.
So actually step 1 is go to fortmatic.com. Login there, then you can follow Fortmatic steps. You should definitely be able to send ETH directly to Coinbase from Fortmatic interface.
Overall this is highlighting a bunch of unnecessary complexity and confusion! I'll work with the team to update our user interface to make all this simple.
