Bike in use by other zwifter missing on companion app

Hey brains trust,
I’ve noticed that when I use the companion app to check up on people riding (not fan view, just the data on companion) sometimes the bike they are riding isn’t listed and other times it is. Anyone else noticed this or know the rhyme or reason?

Ah I see one athlete has request meet up and the other doesnt. So it’s either to do with their privacy set up or one of them doesn’t follow me? But I also see another person who doesn’t have the meet up request option but I can see their bike.

Yes very true!
