We have updated Tracker for ArcGIS! The Track Viewer web app is available with ArcGIS Enterprise 10.7.1 and we have updated the mobile apps with a crisp new dark mode basemap. Check out the details in our announcement blog.
With the June update to ArcGIS Online, location tracking will be supported across the ArcGIS platform. See our official blog announcement on the ArcGIS blog site.
We have made the difficult decision to hold back and not release the new location tracking capability in ArcGIS Online with the June update. We felt the capability was just not ready to release and we want to ensure that we provide you with a solid, quality product. Instead we will be engaging in a beta program starting in July.
