Seeing this bug too in Forms version 22.214.171.12492 on iOS only when displayalert is called from viewmodel. Any estimate on this being fixed?
This looks like a bug in Xamarin.Forms, so I'm reassigning. Please bounce back if I'm wrong.
Issue is still reproducible with Forms 2.3.3 and 2.3.4-pre1
I don't get this. _otherPage has no Parent when you pop it from the navigation stack.
- hit button "testing button" (initializes _otherPage and pushes it on stack)
- hit button "Display Alert Other" (if you want to hit this button, you have to hit the Back button (or close) first which removes _otherPage from the stack)
When the page has no Parent, then it's not showing its alert window.
Am I not testing your repro properly or is your repro incorrect?
