UR22mkii--- input 2 not being discovered in ios guitar apps

Anyone know a workaround? It (input 2) can be selected in some apps (Garageband, Line 6 Mobile Pod and Jamup Pro) but several others (Tonebridge, Ampkit, Amplitube) only will work with input 1.

I prefer input 2 as it has the Hi-Z option for guitar. May be it is app-driven and I’m going to have to live with it??

Thanks

Wow-- found a workaround (thanks to OLD post on Audiobus forum):

Open Audiobus.
Select input (system audio- input 2), Effect is guitar app, Output is system audio.
Save setup to folder (for each guitar app that would not recognize or allow selection of input 2).

Pick up guitar, plug in and continue!
