If you can't find your sub-account on Shopee, you can try the following steps:

Log in to your main account: Make sure you log in to Shopee with your main account.

Check your sub-account settings: Go to your main account's settings or profile page and check if there is a sub-account settings option in the "Sub-account" or "Family Member" section. If you can't find it, check Shopee's Help Center or contact Shopee Customer Service for support.

Make sure the sub-account exists: Make sure the sub-account you previously created has not been deleted or disabled. If there is a problem with your sub-account, you may need to contact Shopee Customer Service to resolve the issue.

Update the app or web page: If you are using the mobile app or web version of Shopee, make sure your app or web page has been updated to the latest version to get the latest features and fixes.
