I'm using Dudu OS 3.6 (250823) and I'm experiencing a bug when syncing my GPS with the Waze or Gmaps app.
On the main startup screen, I have to switch from Waze (default) to Google Maps by tapping the "..." button in the center of the top edge, and then selecting another GPS app to refresh and enable it to work.
Action: Switch from Waze to Gmaps, and then switch back to Waze for it to work.
I have a Medeke M6 Pro (7862S).
Thanks for your help.
