Midway on the trip home, I tapped the temperature again, and the displayed WAAG temp began to reflect that location. Great.
But then when I got home, the tap the temperature "trick" wouldn’t change the reflected WAAG location. After about 45 minutes of trying and researching, all of a sudden it worked as it should have.
What’s the "right every time" way to have WAAG reflect where I am, versus some fixed point?
BTW, even restarting the phone wouldn’t fix this when the problem was happening. And the two times I had the problem, I was on wifi, switched to data and that didn’t fix anything, went back to wifi, struggled, and it eventually got set. The "midway home" time I describe above, I was on data, not wifi, and it changed correctly immediately.
