Is that only for the v20 builds or for any LOS ROMs? Tested 2.4 on my G4 again and it does work.
On the v20, unlike when set to 5, the toggle switch actually stays toggled instead of never switching over like what happens when configured for 5.
But it still shows "error" near the switch and never comes up.
Will go post on the microG thread now and see what they say. Thanks.
