Why do I have to keep paying for this app? – Screen Mirroring + Chromecast Review

I purchased Pro Mirror some time ago. I have it downloaded on my iPad and iPhone. Now it will not work because they want me to pay again. I don’t think I agreed to keep paying money for this app on my initial purchase. Updates should be included! I am going to look for a different app that only charges you one time.
