You're the first person in thousands of downloads to make this complaint. We'll touch up that interaction.
That's a bit surprising to be honest. Since It's not exactly a side route or secret path that you run into this problem for. Perhaps people looked at the walkthrough or didn't care enough to comment on it or maybe its only me. Regardless it's usually not a good sign to feel like one needs to check a walkthrough just to do normal story progress. While I do understand not wanting the phone features to be available week one for the sake of easing people into the routine it shouldn't effect a normal story beat as a result. So perhaps make it so you have the tickets regardless of your phone. So like physical or printout or then if you don't want the concert week one make it unavailable then. Either that or have some way to progress the date without just needing to just bail like an ass. Since correct me if I'm wrong theirs no other option but to leave her high and dry at the club if you go week one correct?
