Same here. Once I noticed the gray X, I erased the drive and placed a new TeslaCam folder. That didn’t work. It required a reformat, new folder - and now it’s working.
I hope this dashcam becomes more hands-off with less tending in the future; I’ve reformatted half a dozen times since roll-out. I can envision “needing it” someday and not realizing it has the gray X.....
