If you're on the first week, he declines (because the phone adds more features to the game) so that you go forth and explore a simpler world without phone events. This limitation will make more and more sense the more contents get added to the game.
But once you're on week 2+, just go to the computer desk and click on the phone.
I'm sorry but that's kinda dumb. Ignoring the fact of leaving your phone at home at all times seems unrealistic. But why would you be able to invite someone out to a concert you can't even go to because you refuse to take your phone with you to get in? So what your just supposed to leave mid date and be an asshole because you can't go to the event you invite her too? That doesn't seem like a good design decision if I'm being honest. You should at least be able to enter during the date if nothing else.
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?
