Moving from PluralEyes to Premiere Pro Create Multi-Cam Sequence Workflow

I used PluralEyes for years and had my workflow down pat. When it stopped working – I started trying to use Premiere Pro’s “Create Multi-Cam Sequence” feature. It does not seem at all intuitive. With PaluralEyes – I’d put everything in a timeline, synch it, nest the video, change the sequence settings, scale the video clips, choose the correct audio track, and start editing. I must be missing something because Premiere’s sync is just not that easy to get set up. Most of my projects are 3 hours of footage with 3 cameras. The first thing is that every time I try I get a “could not synchronize one or more clips in the current selection because a match could not be found” error. It doesn’t show which clip is the issue. There’s no helpful info on how to get passed that. But by selecting the clips in different ways I can usually get it to create the multicam sequences. But sometimes it numbers them say 1-7 and then there’s an extra one called ACAM and then there are usually some clips left over that weren’t processed. I drag the multicam sequences into a timeline. Great. But then I see no way to choose which camera’s audio track you want it to use anywhere along the process so far. It always chooses camera 1. My main audio is always on camera three. So I have to double-click on each multicam sequence from the timeline, go in, and mute/unmute the right camera. Then I have the sequence settings to deal with. I shoot in 4k but edit and output in 1080. I edit in 1080 because I like knowing how far I can punch in on shots and this is easy to see by doing it this way. So then – I have to again double-click each multicam sequence, and change the percentage of the video clips to 50% so that they appear full frame in the timeline I’m editing with. This all seems a bit complicated. I know I must be missing something but I haven’t found any tutorials that address large projects. I miss Pluraleyes right now = Any suggestions are welcome!
