Amber and Ollie

I am adding the spoiler tag in case people haven’t checked their IG accounts but I am just wondering, how come they were allowed to publicly announce that they are together waaaay before The Perfect Match even aired? I mean they met and got together here in this show. Like don’t they all have NDAs until the last episode airs? And seems like they announced on some Love Is Blind reunion, I am so confused. Who’s got the tea?
