They are scamming people, I had purchased tiny scanner pro version in 2017, 4.99$ and they stopped supporting it long ago but they completely hide it from their list and now they're trying to cash in from other plans, you will get scammed like 100k people who downloaded the pro version and they milked 500k $ from them without informing them! Unless they give those full access to all the pro features or refund them all, simply don't give these scammers money!
