Whatsapp隱藏最後上線時間

As of my knowledge cutoff in mid 2023, WhatsApp does not have a feature to hide the last seen status. The last seen timestamp shows when a user was last active on the app, and it is visible to anyone they're in contact with, provided they have the user's phone number saved in their contacts.

However, WhatsApp does offer some privacy settings regarding the last seen status:

1. Everyone: Your last seen status is visible to everyone.
2. Contacts Only: Your last seen status is visible only to your contacts.
3. Nobody: Your last seen status is hidden from everyone. However, keep in mind that you will also not be able to see other people's last seen statuses if you choose this option.

If you want to change your last seen privacy setting, you can do so by following these steps:

1. Open WhatsApp on your device.
2. Go to the Settings menu.
3. Tap on "Account" or "Privacy" (the exact option may vary depending on the version of WhatsApp and your device).
4. Select "Privacy" and then choose "Last Seen."
5. Select who can see your last seen status from the options provided (Everyone, Contacts Only, or Nobody).

Please note that even if you hide your last seen status, there are still ways for someone to tell if you've been active on WhatsApp recently, such as if you've recently sent a message or if your profile photo or status updates have changed. Additionally, if you've recently received a message and are yet to reply, WhatsApp may show a "Typing..." indicator to the sender, even if your last seen status is hidden.
