Yes l was going crazy trying to find what was causing it as it would happen intermittently so it just happened that on my backup ipad, it wasn’t connected to Wifi and it didn’t have the lag, as soon as I connected to Wifi it instantly lagged, You can even see the LED meter hang for a split second as it tries to catch up with the music…
It does appear to come good eventually when the Wifi is on but it’s random…
As I don’t really rely on Streaming music except for the occasional request and be it that Apple music is currently having issues, it doesn’t affect me too much, but would like it to be sorted eventually
