I had an application I used for over two years to download files, basically a file manager with built in video player. It worked great because I could use it on not only my appletv but chromecast. Come to find out the last update released for it was done to take out appletv/chromecast streaming. So I asked the author if he was going to issue a fix, no response came from his email, website, nada! So I contacted Apple asking about this feature, a response was to contact the author. I sent them all the emails I sent and then come to find out while looking on iTunes he released part 2 of the application and updated it with those features included. So he abandoned his original work, took out the part people used with an update to basically cripple his own app, then charged 4.99 to get the new one. Once I brought that to Apple's attention, I was awarded credit even after 2 years of using the application. So needless to say, if you have an issue with an author.. do your homework and then contact Apple with all documentation. They will make things right in the end.
