I encounter also GPS issues since last firmware update (FP4.FP4G.A.170.20220920).
It takes now up to 4 minutes to get the GPS position with Waze.
Before the update it was almost instant (never had the red notification waiting for the GPS within the application).
I cleared the cache of the application. I also checked the parameters (Localisation/Accès aux données de localisation) and switched back and forth between ‘Always’ and ‘only when using the application’ for Waze.
