I am, and I think you’re right! I just tried navigating to it again - Tesla, 9140 E Independence Blvd, Matthews, NC - and got the constant looping.
I also put in the Springfield, OR Supercharger as a destination because I was curious, and, after removing all 13-some Supercharger stops in between, it interestingly did not do the looping. Maybe because the distance is so great, there are few choices in routes it would try to loop/cycle through for whatever reason.
Very odd issue. I’ll be curious to discover if this happens to anyone navigating to a non-Tesla address.
