I decided to roll my iOS 8 back to iOS 7 because mist of the apps I use daily were crashing. Now I find that many of my more infrequently used apps (that I had previously uninstalled at some point) no longer appear in the app store. One example is an mp3 player called MyMp3 Player. It had a browser that allowed me to find audio files on the web and download them. Now it has vanished. (I have scoured the app store!) Now all I can find are players that download from something called the "sound cloud"-whatever that is? Anyone know why? Any recommendations for a replacement?
