Interesting one caught me out big time at a big event last night. Difficult to describe but here goes.
I had a play list of 3 backing tracks with lyrics with time stamps (auto scrolling) plus one lyrics only (LO) track at the end of the list which I was singing with a live concert orchestra. I knew I’d need to scroll the lyrics on the LO track by using my finger but that was ok. I’d tested the LO track at home and it would scroll no problems.
On the night I’d performed my 3 numbers fine and then started the final number. As I was singing down the page I tried to scroll it but it just kept springing back to the start in the same was as happens when a non plying time coded track is scrolled. The LO does not have any time coding or formatting in it the 3 backing tracks do have time coding . Major problem as I got to the third verse with no lyrics to read :-(
On trying it at home I discovered if I directly clicked on the track it would scroll ok but if it was auto loaded by the previous song finishing then the error occurred.
I tried this on all of my iPads, 2021 Air 5th gen, 2018 6th gen and Air 1 running iPadOS 16.1 on the newer ones and iOS11 on the old one. All displayed the same fault.
