No network location with MicroG 0.3.9 on LineageOS 14.1/Android 7.1.2

Describe the bug
I’m not getting any network location with MicroG 0.3.9 on LineageOS 14.1/Android 7.1.2 running on a Samsung Galaxy J3 (2016) SM-J320FN

To Reproduce
Steps to reproduce the behavior:
0. Get a Samsung Galaxy SM-J320FN

1. Unlock its bootloader and install TWRP
2. Install LineageOS from https://xdaforums.com/t/rom-sm-j320fn-f-g-m-18-05-2024-unofficial-lineageos-14-1.4672462/
3. Add signature spoofing using https://downloads.nanolx.org/NanoDroid/Stable/NanoDroid-patcher-23.1.2.20210117.zip
4. Install MicroG Services + Companion + Framework Proxy from the official F-Droid repo
5. Grant all permissions in MicroG Companion
6. Set up location by activating all toggles in MicroG Companion (I picked BeaconDB but Positon gets no better result)
7. Reboot
8. Start SatStat (or any other app using network location)

Expected behavior
I should get an coarse/network location through BeaconDB/Positon wifi query

Screenshots
If applicable, add screenshots to help explain your problem.

System
Android Version: 7.1.2
Custom ROM: LineageOS 14.1

Additional context
I’ve installed the XSRG Root X1 certificates from https://www.stoutner.com/lets-encrypt-isrg-root-x1-and-privacy-browser/ but the issue was present before.

Reproduce the issue on the specified Samsung SM-J320FN setup with LineageOS 14.1, Android 7.1.2, and MicroG 0.3.9, then check location behavior from MicroG Companion and SatStat. Done means SatStat or another network-location app receives a coarse location through BeaconDB or Positon.
