I am sending MIDI PC and CC from my iPad via OnSong. Since updating to 3.10/11, PC changes "take" inconsistently. In 2.xx, all worked seamlessly. Now, initiating a program change from the OnSong UI, sometimes works and sometimes doesn't. I cannot detect a particular condition under which the fail occurs -- does not, for instance, fail on bank boundaries, A-C will fail inconsistently -- but always for specific song changes. This does not appear to be an iPadOS or OnSong issue. I am wondering if others may have experienced the same problem set? I should note that I have been using MIDI over USB, but have also tried USB-C -> MIDI and have attempted different adjustments MIDI global settings to no avail. Same behaviors.
