Poor performance from Mega, only on iPad

I have my Infuse connected to mega. It is working fine everywhere except iPad, which is painfully slow. Buffering is making streaming impossible and even downloads offline are taking 30-40 mins for a measly 1Gb video. Same videos on phone and Apple TV are working beautifully.

On iPad, I tried different Wi-Fi and 5G, same results.

The strangest part is, if I open these videos from the Mega app on the same iPad, they are streaming well and downloading within minutes.

What could it be?

What model iPad and what OS?

iPad Air 2022 with iOS 17.1.1
