Build from Unity to Vuforia no response to markers - iOS 14.2

November 29, 2020 - 7:59am #1

I'm having this issue.

When I build it for iOS from unity and run it on iPhone, it doesn't respond to markers.

The run-time message is as follows.

Why does the 'VideoBackgroundConfig with screen size of zero received, skipping config step' occur?

Device: iPhone12Pro

iOS version: 14.2

Mac OS Catalina

Unity 2020.1.15f1

Vuforia 9.6.3

Thanks,
