What you are seeing is most likely the result of an update to the Android SDK that app developers haven't addressed.
Starting in Android P, there were changes to the way apps can retrieve WiFi information.
See: https://developer.android.com/about/versions/pie/android-9.0-changes-all
Similar restrictions also apply to the getConnectionInfo() method,
which returns a WifiInfo object describing the current Wi-Fi
connection. You can only use this object's methods to retrieve SSID
and BSSID values if the calling app has the following permissions:
- ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION
- ACCESS_WIFI_STATE
Retrieving the SSID or BSSID also requires location services to be
enabled on the device (under Settings > Location).
In your device settings, double check to make sure the apps in question are granted location permissions. You can also go into app permissions and select "All Permissions" to view exactly what the app requests.
If you don't see the above permissions, plus location permission, then probably the app developer needs to issue an update to their app. Don't be afraid to contact them through their support channels and inquiry about updates - sometimes they are fairly responsive.
