Yes, I got it to work earlier today. Took quite some workarounds, though, because on Android, Chrome and Brave don't support extensions. And since you need the Keychain extension to log in... (Steemconnect might be added soon)
So I downloaded the Yandex browser, which allows you to install chrome extensions. Then, followed the steps in this tutorial and got it to work.
Stilll haven't managed to get it to work in Firefox, though
