I've had my Model 3 for over a year, and the other day I hit "Navigate" then "Work" as I normally do, and it prompted me for my work address. My work address had been stored successfully for over a year, and now it was gone. Same goes for Home and Favorites (there was also no recent location history). I re-entered them and later realized they were gone again. I rebooted to see if that would help, but they disappeared yet again. I got 2019.16.2 a few weeks ago, so that can't be it, entirely. I did, however, decide to live on the edge and switch my Software Update preference to "Advanced" around the time this started happening. I switched back to "Standard" Software Update and rebooted yesterday. This morning my locations were still there. Coincidence? It doesn't feel like it. Anybody else experience lost locations?
