Typing this on my Poco F1, 6 may ROM and now upgrading to 13 may version. Battery is great (2,5 days), it is very stable and the speed is also good. Yesterday I've tested navigation by downloading Google Maps. Couldn't find places by typing. When I enabled advanced location via WiFi and Bluetooth it worked. Installed in November lineage manually with MicroG and had problems with finding location. Not anymore.
I also use Aurora store for the few apps that I'd like to use from play store such as banking. The sick thing about this combination is that it supports in app purchases as well.
Do you also get this annoying thing where the fingerprint sensor stops working sometimes and touch is too sensitive? The LineageOS beta worked great, the official version is buggy for me and is really annoying.
