Hi Community.

I am experiencing a glitch on mobile.
Reproducing the glitch:

1. search for an address (the map zooms automatically to the searched place)
2. zoom out slow or fast (map turns/flips upside down)

Can you help?

@worldpeaceenginelabs I am unable to reproduce this bug on mobile in Cesium Sandcastles. What device are you seeing this bug in? Are you able to reproduce this bug on that device in a Sandcastle too?

I also saw a similar glitch as @worldpeaceenginelabs on iOS. What I did was created a WKWebView and loaded the CesiumJS webpage via the URL. Next, I search for an address, and CesiumJS then flies to that location. Then when I start pinching-n-zooming, the map rotates quickly (or does a fast spin) at the center location where I am trying to pinch-n-zoom in.

@ebogo1 Sorry for answering so late.

Yes, it seems to be device-independent, since it does it on my mobile, my tablet (both Android), and now on IOS too.
@wisdomware did you do it with my app? Do you think it's a bug in my code or a general bug in the Cesium code?

Due to lack of activity, I'm going to close this issue. @wisdomware @worldpeaceenginelabs If you have any update, feel free to reopen it. We're aware that touch controls in general need some attention, see #4363, so please add a comment there if relevant.
