The Instagram app doesn't open on my phone

Yes, I have contacted them as well

But my problem is still not solved

My Instagram doesn't open, the problem is with the app

The problem is that I don't have an account

So please fix it for me. There is no Wi-Fi problem

Did you already contact the Instagram Support about that?

Are you connected to Wi-Fi or the mobile data network?

Sorry, this is a user to suer forum, we can't fix any apps from the AppStore, only the developer of those apps can do that.
