connecting the ur242 to an ipad/iphone etc

This is very flaky and I suspect it’s more to do with Apple than Steinberg. I just can’t get my UR242 to work with anything that has IOS 11.2. Sometimes it works on input 1 but not 2 and other times it just doesn’t work at all.
Any ideas?


I haven’t fired mine up in a while. Which adapter are you using?
