This is a fairly recent thing, but my running logs are a bit weird. The total distance and time seem correct, but on the map screen at the top, where it shows details of my run, it only shows about half my run - this started a week ago. I'm using a Pixel Watch 1, and my app is up to date on my phone and watch. I make sure that the GPS is connected before starting to run. I've rebooted both devices and cleared the cache, but the map still doesn't show my full run.
