Multitouch doesn't work in web browser 4.21.2

Multitouch doesn’t work in build-in web browser 4.21.2.
Multi touch works fine in widgets but in web browser it doesn’t work.
I’ve tried to integrate google maps into my app, and when i’m trying to zoom map in or out with two fingers - it doesn’t work, it seems like unreal gets the last finger input and ignores my second input.
In web browser (Chrome) in windows google maps work good with multitouch.
Maybe it depends on web browser version? If yes, how can i update unreal build-in browser?

Did you find a solution? I have the same problem with UE 4.25.1.

No, still have no idea :frowning:
