Hope this is the correct place for Beta bug report.
While traveling this past weekend I had problems with the mapping feature. After I would power down the bike and turn off the screen on my phone, when the phone would wake up the map would lock up. The location arrow would turn to a small blue dot, and there would be no map motion once I started moving. A few times this would resolve on it’s own, but most times I would have to re-start the phone to fix it. When this would happen, other nav apps were still able to update location so I doubt it is a phone GPS issue.
