N26 banking app cannot get location

**Describe the bug**
It is not possible to open an account with the N26 banking application `de.number26.android`. One of the steps of the verification process tries to obtain the location and fails.

**To Reproduce**
Steps to reproduce the behavior:
1. Start the process of opening a bank account on the [N26 web page](https://n26.com/en-eu)
2. Install `de.number26.android` on the phone
3. Try to complete the verification process on the phone
4. Observe that the step that requires geolocation fails

**Expected behavior**
Verification process obtains location information and completes successfully.

**System**
Android Version: 10
Custom ROM: LineageOS 17.1, official build
microG: 0.2.16.204713 installed via nanodroid; all self-check boxes are ticked
Location providers: Déjà Vu, GSM, Mozilla, Nominatim

**Additional context**
To check whether location services work at all, I used SatStat which properly shows both red and blue location markers. logcat output when running SatStat is quite different than the one when running N26, though. Can I (or shoud I) use another application to test?

Below is an excerpt from logcat while performing the location step of N26 identity verification, with coordinates redacted:

```

Start by tracing the location request through GmsLocProviderReal, GmsLocProviderU, and UnifiedLocationClient.kt using the supplied logcat sequence. Reproduce the verification flow with de.number26.android and compare its behavior with SatStat. Done means identifying and fixing the cause of the failed location step, then confirming that account verification receives a location successfully.
