cookie Banner

regarding my problem with the missing preview when posting youtube videos in the feed:

when Real Cookie Banner is activated, no preview from the youtube Link is shown (although i accepted all the cookies, etc.) and though there is some grey space (the place where normally the preview is shown), you can't click anything except the link in the text.

When i deactivate Real Cookie Banner, everything stays the same for existing posts, but the preview is shown in new posts that i create afterwards.

Anyone in here using a cookie banner and facing the same problem?
