Thanks for letting me know. It sounds as though it could be the browser you are using. Could you please clear the cache on your browser as mentioned in this guide or use a different browser/device and try again? If you still can't see the store's after you log in, please log out as shown below and access our support (here) as a guest instead as mentioned shown in this video.
Let me know how this goes and if there is anything else I can help you with, I'm happy to help!
