Have you tried switching off Wifi?
For me, it’s instant, as soon as I switch Wifi off, it returns to normal, switch it back on and it lags…
But if I leave the App on and Wifi on for an hour or so and then come back to it, the lag also disappears until I close the app and restart it.
This is with iPad Air 5th Gen and Denon Prime Go (But also tested the same with my Rane One)
