I saw the white screen only when I tried to launch the game without extracting it from the game archive. After that it worked without any problems in opera or chrome. What kind of errors did you see?
Oh I found where the problem was.. It was my file manager ig that mi file manager have some problems with it so I tried some random file manager from Google play and it works perfectly fine :))
It you can use anything but I used File Commander Manager & Cloud on google play and allow javascript on your browser idk where is it on other browsers but its in site settings on chrome gl and I hope it will work for you too.
Did you need to do anything else to get it working? I've already tried a couple browsers checked for everything else you mentioned but can't get it working on androi
