Hello,

Our website have "cross-origin isolation" setup, more exactly included the following in response header:

Cross-Origin-Embedder-Policy: credentialless Cross-Origin-Opener-Policy: same-origin

but now, the youtube video which is embeded in iframe is not working(blocked)!

How to solve this problem?

Can you link an example or simplified test case?

Did this ever work previously?
