I was having issues too until I realized that the check in interaction is actually checking in with other Sims and using the stylist related interactions with them such as modeling looks and talking about fashion. They could have worded it differently for sure.
this issue here was fixed but there have been a few people complaining now about the misleading info given.
Could you please create a new thread for that ?
I'm going to lock this one.
Please only contact me via PM when asked to do so.
