Tonex Capture box and Apollo x4 - what I/Os to use on Apollo?

I swear I’m following the directions right… Guitar into HiZ input of x4, Line 1 out of x4 to ToneX Line In, Tonex To Amp to my amp. I get my guitar signal coming through Console and into my monitors, but the signal does not go to the amp. Is there something in the I/O matrix I need to do? I tried routing the MIC1/LINE/HIZ1 to Line 1, but that didn’t do it. Any ideas/tips would be greatly appreciated! Thanks!
