Can't Access My Timo Account After the App Update

I am using the Timo app on my iPhone in Malaysia and can no longer access my account. Previously, I always logged in with the “Sign in with Apple” option. After updating the app, the login screen now only shows “Sign in with Google”, so I cannot enter my existing account anymore. Because my account was created via Apple, I have no way to log in using Google, and I do not want to lose my previous data and usage history. I did not make any changes to my account; this problem started only after the latest update. I request that my access to my existing Timo account be restored and that either the “Sign in with Apple” option be added back for my account or another secure solution be provided so I can log in again without losing my previous data.
