Bought Gas Cubby Pro a long time ago and now get hit with a subscription?

So tonight I got two emails about this issue. Gas Cubby lite users will now have to pay a monthly or annual fee to keep the app ad free but existing users that bought Gas Cubby Pro before Dec. 11th 2017 the app would, supposedly, remain free. So I should be okay...

So, not having opened the app for a few days, I open the app and sure enough I immediately get a message shoved in my face to upgrade to Fuelly Premium. It said in the emails that if that were to happen, I should just force close the app and try again. So I did. No nagscreen. But, in the burger menu, the bottom item is still "Upgrade to Premium".

Anyways, I'm not a happy camper. I bought Gas Cubby Pro a long time ago and yet... here I am.
