I wonder why my review was deleted, Stopped working suddenly, then started to display advertisements even though I purchased this last year. Some of the conversions no longer work. I asked for assistance here and at their contact email four times over a month now, never got an answer but my review was deleted.

Purchased this app on April 18th, 2021. Worked fine till I tried it today, adds started appearing, currency converter does not function. I checked my version, and it was 4.1.0, Uninstalled and re-installed, same version, still the same problems. Its telling me I need to upgrade to Pro version which I did in april of last year. Am I supposed to pay for the app again? I can see other have had these problems I'm having.....

Won't convert currency. It did when first installed but hasn't for a long time. Other calculations work no problem
โ˜…โ˜†โ˜†โ˜†โ˜† Linda Elkins ยท Mar 23, 2023
I've begged for someone to explain why I am getting ads and being asked to purchase the premium version when I purchased that version 3, 4, maybe even 5 years ago. This app worked fine up until this year. Was there a cut-off of the time period for the premium version. If so, that wasn't stated when I originally purchased it. Quit telling me it may take a day or two. It's been years!!!! Please tell me why I have evidently been removed from the "premium" version?
