Skype now with a video call sometimes shows ads instead of the image of the interlocutor

This morning I updated Skype, which promised to become even better and more convenient after that, and an hour later I made my first video call to my wife. And that's what he saw instead of her face. The principles by which this advertisement appears or does not appear to me are not known. From 3 attempts to make a video call, I saw an advertisement on the site of the image of the interlocutor all 3 times.

PS I'm sitting at the American VPN - maybe this is the case?
PPS Found a mention of advertising here . There, however, it is claimed that "... there will be no sudden pop-ups or screaming banners in the middle of the conversation."
