I figured I'd make this post for anyone who held out like me to wait until everything settled down. I decided to grab the digital CE today from Square's NA store, unlocked the code in my product page, went to enter it and got the already used message. I tried the tricks from Reddit about entering the dashes as spaces/underscores but not even that worked. Support is incredibly difficult to reach so I figured I would at least post this here as an update/warning that if you plan to buy the digital CE from the store you're still going to experience the same troubles as a few days ago.

I should have waited for Amazon to start selling it.
