Loss of geolocation and navigation on tablet

Hello,

I've been experiencing a problem with the location function on a Lenovo Tab P11 (2nd Gen) tablet for the past few days.

I no longer have anything. That is to say, for tracking applications (Locus Map, Garmin Connect...), the cursor no longer indicates the device's position.

I also note that my phone loaded with these applications works normally.

The location access for these applications is checked to "Always allow" for the tablet.

I installed 2 applications (from the Play Store) on the tablet that test GPS. The first one gives me: GNSS Status - None. The second indicates: GPS disabled - The mobile device does not have a compass. It disables the compass function in the program (of the application)

My question: how to reactivate the GPS or the location function of the tablet?

Thank you in advance for your advice.

C.
