GPS points are currently not uploaded to the cartouche.
this started on July 22nd, for world.waze.com this started on July 11th.
The reason is performance issues due to many new GPS points and the system not being able to handle them with the current settings.
We are revising the GPS points and will upload all the missing ones as soon as we have the improved architecture in place. No GPS points are lost, and you can still see your routes (from your archive), but you will not see any GPS points there. We apologize for the inconvenience, and hope that the new settings will also allow for a faster cartouche work with the GPS points.
