New MBP, 13in, M1, 2020 Big Sur 11.1. At various time cannot drag highlight (which is what I've always done with my Macs/PCs). If this isn't fixed before my return deadline, I'm leaning towards a return. I'll just continue on my 2012 MBP.... Also I notice Internet speed/connection drops from my Comcast router that the 2012 MBP doesn't experience along with slower processing of commands using Chrome. These are all everyday use deal breakers for me. What other issues haven't I found?
