I Can’t Log Into My Existing Pi Network Account Linked to Facebook

I originally signed up for Pi Network using my Facebook account, and everything was working fine. Now, when I try to log back into the app using the “Continue with Facebook” option, it redirects me to create a brand-new account, even though I already have a verified and active account.

I know my username and password, and I can even see my old account details, so I’m sure the account still exists. However, I simply can’t access it through the app anymore. This issue is incredibly frustrating, and I’ve found no clear support or solution from the Pi Network team.
