Well in my case the FB post did affect me as we were dating and all of a sudden no break up just him in another relationship. That's what Yona saw as an update I would get.
It’s different if they specify that you’ll get an update, that makes sense, that’s not the same as them getting into contact with you. If someone tells you that you will be in contact with someone/ they’ll reach out to you and what actually happens is you see them put something on their own social media that doesn’t include you, I don’t see how they can be considered right. That is really stretching the meaning of “contact”.
But the fact is that we are expecting the psychic to know what they are seeing. They get bits or pieces or just see something the do or say affecting us. It is what they may guess is contact but isn't always the case. Yonas words before it will be an update were that I would hear from him again. That it wasn't back and forth it would be an update. The majority of psychics guess at the little they can see.
Maybe it’s only specific to Yona but I agree with @maggs30 that Yona does consider updates or posts on social media as a form of “contact”. In my reading Yona said I would get contact from an ex or a person of interest and it wasn’t a message being directly conveyed to me and there was no strategy behind it. Yona specifically talked about the contact was by seeing photos on social media. I will add that Yona repeated this twice in my reading and used the word contact via social media.
When we think of the word “contact”, we’re hoping a psychic is talking about physical direct contact but “contact“ is so broad. A psychic really needs to describe the circumstances of the contact rather than a broad statement like, “you will be hearing from your poi.” In today’s world most people are spending their time on social media and posting updates about their lives. Lots of people like millennials or Gen Z who spend a lot of time on their phones do consider social media as a form of contact.
