Premium Version

I upgraded to Premium version on the Web App, but my IOS app is not showing as upgraded to Premium. How do I get the IOS app to honor the Premium upgrade I purchased through the web app?

I attempted to “Restore Purchase” in the User Settings on the IOS app, but I get the message “Sorry, it doesn’t seem like you have upgraded. If you believe this is an error, please contact support from the menu.”

Please msg me your email or username. Thanks
