Why am I being forced to pay again?

*** Warning *** DO NOT DOWNLOAD THIS APP IS A SCAM ***!

I paid for Plotagraph in full, I had full access to the app including no watermark, now after the last software update- you have forced a watermark back ?? And there’s no way to remove it without signing up for a monthly paid membership? What the heck happened to this app? It turned into a money making scam ?? Better let the world know about your scheming now ...
