You missed my point of posting yesterday - I
chimed in several posts earlier that the additional detail is showing up in the macOS app, adding later that it's not in the iOS app yet.
As to the "wandering" of GPS, yes it has annoyed me over the past several weeks but an experience today left me wondering somewhat. I was out in my older Benz today and used its clunky nav to get to a location in its memory - and I'm just spitballing here - the COMAND unit was locked onto
8 satellites (it shows in the display) and the nav was acting just as my iPhone has been, as if it were dozens of feet behind my actual position or not on the roadway. Turns were announced after I'd made the turn, distances were off by dozens of feet, at intersections my position was "floating" - all with a clear line-of-sight. I took my GF's Porsche out, a fairly new Macan, and got the same positioning issues while locked onto 7-8 satellites. Then, I broke out my surveying total station - which uses the E5 GPS frequencies, generally good to around 30cm on a bad day, and I couldn't get a lock. None of those units use a cellular network - satellite only. Something's up, seeing what you offer as "wandering" as well - and GPS.gov is in shutdown mode, of course. I've got to survey a site next week, time to break out the hub and oil the chain... /rant
