To start off, I used to use Uber using there HTML5 web app - they call it “web booking”
They turned off “web booking” access to booking a ride.
Not sure if “web booking” booking is still available elsewhere, it still worked in Manchster last time I was up north
Thier native app )which you can get from Aptoide) works with MicroG but sometimes the map looks wonky and it shows errors
They still accept the ride request and I still get home though
On a side note:
I’d recommend not to use Aptoide, because previously there were flaky apps / sources.
It’s probably more safe to use Aurora Store, which you can download and install from Jolla store and is just a privacy-friendly frontend to Google’s Playstore. You don’t need a Google account to access through Auroa Store.
Maybe they do it periodically. I remember having trouble using their web page some years back in Glasgow.
It worked flawlessly in Manchester last month.
Looks like it’s also working when I enter a starting point and a destination within London:
I don’t want to toot my own horn too much, but if you’re using trains alongside Uber (or public transport in London or Manchester in general), there’s an app for that: openrepos.net/content/anarchyintheuk/multimodal
