Hey, @matthewgx
The first thing I would suggest would be to try to access the app from a different browser (Google Chrome or Firefox) then you are using now and clear your browser’s cookies + cache files. This will help rule out any potential local issues on your end.
If it still doesn’t work, your next best bet would be to contact the app developers directly for a status on their app.
If there is anything else I can help you with, please let me know.
