Logic Pro for iPad input stopped working

I've been using Logic Pro for iPad together with Audient iD44. Worked perfectly for some time, but now Logic will no longer recognize the audio input from Audient. The only option is iPad's microphone.

Firmware on Audient is up to date as well as the latest iPad update. The iD44 works well on a PC. I've removed and reinstalled Logic, rebooted, checked all the settings on iPad for Logic. Can't think of anything else to do.

Anyone experiencing similar problems? Grateful for any support on this.
