Using version 4.2.3, the screen is blinking alternatively between the map and the navigation info.
Phone : LG v60, Android 11 stock
Thank you for reporting. This is an issue we haven't seen before but I am currently in contact with another user who's described the same behavior on their samsung galaxy s10.
If you interact with the app (if possible) are you finding any way to stop it? Or are you seeing anything that starts/triggers the flickering?
The flickering starts directly when the app is launched. It seems to be linked to the bottom sheet (that can be slided up).
When it is slided up entirely, there is no more flickering.
But when displaying the map it happens again, and I haven't found any way to make it stop unfortunately, the app is currently unusable.
