Camscanner was a blatant bait and switch. When I first started using it, I paid for a license to get full functionality with no ads/watermarks/etc. Magically, years later I got reverted to the ad-supported/free version, and my license was nowhere to be found. This was at the same time they moved to "cloud features" and a subscription model. Their reviews are littered with people having the same issue and the developer copy-pasting some response that doesn't work.

I haven't had this issue with Camscanner, but I've had it with other apps. One outright disappeared from my library, as if I have never had it installed.
