Rae from Shopify here.
Thanks for letting us know about this error, and for trying to verify your email address by following the steps in our help document.
Since you didn't see a verification option when following the above steps, I recommend trying out these steps instead:
Once you complete this, it can take up to an hour for the verification to process correctly. After this time has passed though, please clear your browser cache, and then try to access the Exchange Marketplace once again.
Let me know if this resolves things on your end!
This is an accepted solution.
