UR22C DAW monitor delay with Cubasis2 on iPad

I just bought a UR22C. Using it with Cubasis 2 on my iPad Pro there is a nearly .5 second delay between the DAW and Input settings on the MIX Knob. I tried my old UR22mkII and there is no delay between Direct and DAW monitoring. And when I connect the UR22C to Cubase 10 on my iMac there is also no delay. Is there an inherent issue of delay when the UR22C is connected to Cubasis/iPad? Or is there is setting that I’ve missed in Cubasis2, UR22C or my iPad that will eliminate this delay?

Thanks for any help! - Jim
