I guess we will need to wait till they fix the bug before continue playing the story! I hope they will fix that soon!
They almost certainly have fixed it already. It's just that the phone doesn't work properly for certain people because of an incompatability issue with Windows 11, which mean the bug fixes won't help them. I know this, because I'm one of those people. And it's incredibly galling, because I can't play my favourite game, the way I want to play it.
When the phone was implemented, the Devs made some errors, that they didn't pick up on for a number of updates. Because it took that long before they started to cause a significant issue. And that was old saves failing to work for a lot of people. And it took them a few more updates to work out why. That's why they're now saying that all future quests will be completely separate from the phone. Because trying to correct the flaws in the phone is difficult, and risks creating new ones, which might screw the game up completely. Unfortunately, that means for some of us, until they separate quest content from phone content, we won't be able to play the sandbox version properly. Some people manage to play some of the content, albeit in a screwed up fashion, whilst for others ( like me) the game just stalls completely, with no way forward.
Fortunately, there is an alternative. The VN version is not affected by the phone issue, because the phone isn't a part of it. And that means all bug fixes work for everybody. So you could try that, if you haven't already. But you would have to start again from the beginning of Chapter 2.
