Can't get ipad to recognize disk mode

Any help appreciated. New 7th gen ipad running 13.3.1. Apple CCK is powered. Trying to opfun and offload tracks/album on the go.

It’s plugged into the power strip like in the photo. I’ve been using the CCK to feed op1>zoom6>ipad to track into cubasis which is usually successful.

Try the old unpowered CCK? Get a USB hub? What am I missing here?
