I have just upgraded to the Stagetraxx3 from the 2.10 version which I have been using since 2015 with my iPad 4. I have had no problems at all and the app has been amazing and worked seamlessly with the iPad 4.
After transferring all my backing track music files over to the new iPad 10 and testing them, I noted that quite a few are missing the first half a second or so at the beginning of the song. It doesn’t seem to happen when playing via its own speakers, but only when connected via cable to my Bose T1 system. Hope you can shed some light on this for me to get this resolved. Many thanks.
