I was resizing ST4 in iPadOS26 snd was playing around with the sizes and trying to fit both ST4 and Spotify
on the screen and I noticed that scrolling and highlighted lyrics dont work.
The scrub bar also was very out of place (showing song was about halfway but in fact the song was in the beginning)
I tried to replicate the problem without Spotify and seems the problem is only with another app in the background.
Scrubbing the song back or forward fixed the problem.
