GCash issue: Existing account suddenly shows “New Account”

I already have an existing GCash account, but for the past 2 days, whenever I open the GCash app, it goes directly to the “New Account” registration page. There is no error message and I can't access the login/account that I used before.

I already tried clearing the app data, reinstalling the app, and restarting my phone, but the problem is still the same.

I also contacted GCash Support, but the available concern categories don't seem to match my issue, so I keep receiving unrelated/automated responses.

Has anyone experienced this before? How did you get your existing account recognized again? Any advice would be appreciated. Thank you!
