Ok, that’s a possible avenue of investigation, which also in developer land. However, a bad web page should not bring the browser to a crash, so there is something to be changed on the SFOS side as well
In my case, AngelFish doesn’t crash. It just ends at the page shown above and offer no way to allow camera use.
Regarding the stock browser, on my XA2 Single 22.214.171.124, the browser does not crash nor freeze.
I goes to the conference with disabled camera and has no reaction when I try to enable the camera by pressing the the strike-through camera button.
