Bought subscription and it’s not working. Says I’m a Free version user

[#1]

I recently bought the Premium version and it worked last month but now I tried to use it and it says I own the Free version. I'm clearly subscribed since it charged my card and my subscription automatically renewed but it's not allowing me to use it. I tried uninstalling the App, clicking on the trial option (says I'm already a paid subscriber) and nothing is working!! Help!!!
