I Can’t Log into Line—Phone Number Not Recognized Despite Verification

I’m unable to log into Line. Although my phone number is verified and I enter it correctly, the app says my number is “not registered.” I don’t know how to proceed or access my account. I’ve also tried logging in with my email and Google account, but none of these methods work. I even reinstalled the app, but the problem persists. This is very frustrating because I rely on Line for communication and now can’t use it at all. Line support, please help me resolve this login issue quickly. I need clear instructions or a fix so I can regain access to my account without further delay.
