Hi guys. I made a quick edit.
Look at 3.1 above and also look at caps locks in comments. You have to actually sync 1 at a time and always in the same order for best results.
You might have to attach usb cable first times if you’ve lost sync so it can recatch then reboot and always sync in same order. Let me know if you get different results.
And sorry no idea about error messages you are getting as I am not getting those.
Cheers.
