Virtual background and filter don't work in Mac os

at same mac os(Big Sur) and same app with sdk v5.2.41751.1026. the virtual background feature is valid, but today I found it does not work in same zoom account. After upgrade to latest version v5.2.42037.1112 SDK, this issue is still existing.

  • - (BOOL)isVideoFilterEnabled;
  • - (BOOL)isSupportVideoFilter;
    both of these function return YES.

But the same sdk in windows, it works well.
we try with Zoom’s client, and found zoom client disable virtual background, enable filter.

whether zoom disable this feature in server site?
