No GPS fix for most apps

Expected Behavior

Apps can acquire the current location.

Current Behavior

On LineageOS 17.1-20210406 and OpenGApps mini 20210407, "GPS Status & Toolbox" does get a proper fix in reasonable time, but most other apps don't, including Google Maps. The apps have all been granted location access, and "Google Location Accuracy" is enabled.

Another exception is the nightly build of OsmAnd, while the latest release (3.9.10) does not. One notable change between these versions is that the dependencies were bumped from 'com.google.android.gms:play-services-location:17.1.0' to 'com.google.android.gms:play-services-location:18.0.0', but I'm not sure if that's related.

I'm uncertain whether this is an issue in LineageOS or OpenGApps. Any pointer in how to debug this further would be greatly appreciated.

I have read the directions.
