I gave it a try and tested out multiple weeks of attempts in a row, but seems like my Ana is locked to never do gigs unfortunately. She'll dance with the girls in school, but no matter how many times I engage in discussion with her and Dani again, it's just the same repeated conversations. They're already reconciled and Ana is just done with events. Unless I have a bug, idk. That's also just as possible.You need to talk to Dani a bunch until Sammy thinks that she needs to get them the reconcile. Then you need to talk to Ana a while, with some Dani mixed in as well IIRC. It takes multiple times talking to each but eventually Ana will say she'll start going out on gigs again.
I'll probably test out using the cheat to roll back the dance event and see if that works. One notable thing about Ana currently is that she has no solo times to talk and no longer has the gift menu option for me anymore. She's locked into only talking with Dani and it's limited in what the conversations say.
