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,
