Must fix paid Version! – Light Meter Free Review

I deleted the app then reinstalled and adds reappeared but function returned. There was a quirk but then I gifted the cookie and all is good now. tried this app and preferred to others in it's class. Then made the mistake of buying Beer Mug. Ads gone but App no longer functions. Once opened the exposure never changes. From light to dark. Tapping has no change. Must close App then reopen for new reading. Please fix this bug. Functioning App with Ads is preferred. Upgrade ultimately worked after deleting and reinstalling app.
