My Android app shows that my Pro account ( expired on 04/05/2017. When I press Upgrade to Pro Google Play says "Error: You're already subscribed to Pro Service".
I paid for Pro on April 11, 2017 via Google Play:
Order number: GPA.1397-8628-4492-31246..0
Order date: 11.04.2017 13:39:34 MSK
Next payment scheduled for April 11, 2018.
Why did my Pro account expired?
