Guesstimating the install text position works and I was (eventually) able to update all my 10+ Android apps I have installed via Aurora Store. My tactic was repeatedly tapping from a bit too high to a bit too low, one of the taps should hit the button…
Edit: Can someone with 4.6.0.11 test this and see if this is a regression from that version ir not? IIRC this worked for mw with 4.6.0.11 but I’m not entirely sure…
