So this is weird, I thought I had figured out a workaround until you had a chance to think of what to do (if there was a point to doing it). I thought if I set the lyrics to the standard size (reset text size) but pinch zoom and “save text size” for the chords, I could then go back to settings > appearance and set the override to 80%. I figured since the override wasn’t affecting the chords, they would remain at the pinch zoom size and the lyrics would be at the 80% size. But when I do that process the chords show up at 80% of the pinch zoom size. On top of that it appears to affect songs that I didn’t pinch zoom the chords on. So if chords and lyrics are both at the standard size but at least one song has pinch zoomed chords all the chords in the setlist are affected by the override.
I will try resetting all chords and lyrics then just pinch zoom one set of chords just ever so slightly, maybe 99% just so I can “save text size”, then try to override. I’ll let you know.
