Sorry if this has already been posted. Trying to catch up.
Pioneer has updated the IControl app in March, just found it now for apple products. Its called IControl AV 5. It is now back compatable with the SC 1222, SC 1522 and many other older recievers. Thanks to the many owners that emailed Pioneer and kept on them to make a universal app. If you feel up to it. Take the time to rate the new app. Its a good way to thank Pioneer Engineers for doing this.
