If you changed the mobile number on your GCash account, update the linked wallet details on Lazada to prevent login failures and authorization prompts going to the wrong account.
In Lazada, go to your account settings and open payment options or digital wallet settings, then select GCash and follow the login prompt with your current number.

After updating, run a small checkout test (without rushing) to confirm the authorization flow works and the correct wallet receives the prompt.
Keep your new number active and ensure you can receive verification prompts needed for secure payment confirmation.
If you no longer use the old number, unlink it to reduce confusion and avoid accidental authorization requests.
