Hello team, I want to purchase your master subscription, but I can't buy, because this massage is showing 👇 (this app isn't available for your device because is was made for an older version of Android) I hope you guys solve this problem

★☆☆☆☆ Bharat Kapoor · Jun 21, 2020

Really a great application... But whenever click on any option. It's showing upgrade option... You guys are forcing us to buy your so-called "Master" / "pro" Application version. So cheap... Shame on you guys.... Too many obstructions (advertisement) while running the app.
