VST Connect & VST Connect SE - Solution Thread

I’ve read quite a few post here, but haven’t seem to come across my problem yet. i can use vst connect template in the hub and hear, record and playback with my partner no problem. my situation is trying to create a vst connection within a existing song. i can see my partner and he can see me, but no audio at all. everything is setup correctly in the vst connection cue settings, tb track, monitoring track etc. i watched the video and did exactly what they did on a “new” project and worked, but can’t seem to get it to work on a track that i made months ago. can it be done on a existing track? i say it has to, i just can’t do it right. anybody?
