John, some frustration lurks with every advance.
You’re describing a fundamental technique that you need to correct - knowing which finger to place down and being able to pick the correct string. When you have a technical problem, when you are unable to perform the mechanics of a task, you do not want to be using a metronome at any speed. You need to be able to physically follow the technique first. So set aside the bpm counter and just train your two hands to coordinate.
Also, imho, it sounds like Yousician is a hindrance not a help, like it is not learning to play guitar, it is a game.
I just looked back at your topics and a similar theme is clear - you still seem to be lacking focus, not on the structured learning path (the JustinGuitar course) and are still dipping into too many youtube tutorials that are taking you off in different, random directions that are not supportive of, or complementary to, your core learning needs at this time.
