I just tried it and it seems to work just fine calling Firefox Focus instead of Chrome.
let’s not rush it this time 
works fine for me too – Android 7 with Firefox Focus as default browser
I am not sure, did the color change slightly?
e: just compared with my tablet, the new version has a more saturated blue – I think both are fine 
some slight css changes are coming with the pdo changeover, this just unifies the colors
well i’m not seeing any unusual crashes so i’m going to slowly start rolling this out to stable
fingers crossed, etc
