I'm sorry to hear that you are having trouble submitting your profile for review. Have you tried clearing your cache and cookies and trying a different browser?
I am having exactly same issue – stuck on 'Create profile page' and have waited for notifications for next steps but still nothing.
Can I please raise this and request help?
Did you already tried to clear your cache and cookies or log in with another browser to resubmit your application? If you already tried this steps please let me know what browsers you used as well, thank you!
