No known location despite all self-check boxes and multiple backends installed

There is "no last known location" despite all boxes checked in self-check and multiple backends installed.

To Reproduce Backends installed: Deja Vu Location Services, WiFi Location Service, Mozilla Location Service, Radiocells.org. "Use location" and "Wi-Fi scanning" are both checked/enabled in Android settings.

Expected behavior I expected a location to be retrieved.

System Android Version: 9 Custom ROM: LineageOS 16

Additional context NetworkLocation.apk installed via adb push

Same issue here pn Redmi Note 7. Lineage os 17 for microG .

Never mind, location services work now.

Another never mind, it's half broken. It works some times but I have no idea what triggers them.

I'm also suffering from this bug after updating to e-os 0.13 . Position using wifi is working much worse now.

@warriormaster12 came accross the same issue, but with Unified.apk (not NetworkLocation.apk). I could fix it in Android 10 by enabling / disabling the backends after a reboot. Maybe you could try this?

Same issue on Oneplus 8 Pro (instantnoodlep, IN2023) with LineageOS-for-microg 18.1 (2022-04-04) and Mozilla Location Service (Mozilla UnifiedNlp Backend, org.microg.nlp.backend.ichnaea, 1.4.0) and Nominatim.

Tried to detect location inside buildings and outside:

App	Network Location (inside)	GPS (outside)
Maps sites in Google Chrome (Bromite, v100)	fails	works
Organic Maps	fails	works
GPSTest	fails	works
My Location	fails	works
OsmAnd~	fails	works

Update 1

Performed some testing w\ Mozilla Location Service (1.4.0) and Apple Wi-Fi (org.microg.nlp.backend.apple, 1.2.3). It kind of works, but unreliably. Both got my current location with decent 22-30m accuracy, but both also refuse to work constantly. They give longitude and latitude around 1 time per hour and "fail" to work (as "My Location" com.mirfatif.mylocation tells) every ~10 minutes.

Once in a while logcat logs error messages like that: java.lang.IllegalArgumentException: Receiver not registered: org.microg.nlp.api.WiFiBackendHelper

App	Network Location (inside)	GPS (outside)	Glonass	BeiDou
Maps sites in Google Chrome (Bromite, Ungoogled Chromium, v100)	fails	works	doesn't work	doesn't work
Organic Maps	works unreliably	works	doesn't work	doesn't work
GPSTest	fails	works	works unreliably	doesn't work
My Location	works unreliably	works	doesn't work	doesn't work
OsmAnd~	fails	works	doesn't work	doesn't work

Another logcat log message I see often is Received no location from org.microg.nlp.backend.ichnaea/.BackendService
