Hi
Apologies for the long post
. Disappearing Messages Feature:
WhatsApp has a "disappearing messages" feature that allows messages to be automatically deleted after a set time (24 hours, 7 days, or 90 days).
If you've enabled this feature for a chat, messages will disappear after the designated time.
You can check if this feature is enabled by opening the chat, tapping the contact's name or group subject, and then selecting "Disappearing messages". If it's enabled, it will show the selected time period.
2. Accidental Deletion:
If you haven't enabled disappearing messages, your messages might have been accidentally deleted by you or someone else with access to your phone.
You can try restoring your chat history from a backup to recover deleted messages.
3. App or Device Issues:
Sometimes, WhatsApp might encounter bugs or glitches that can cause messages to disappear.
Restarting your device or reinstalling WhatsApp might help resolve these issues.
You can also check for updates to both your phone's operating system and the WhatsApp app.
4. Restoring from Backup:
If you have a backup of your chat history, you can restore it to recover deleted messages.
To restore from a Google Drive backup:
Uninstall and reinstall WhatsApp.
Sign in with your phone number and verify it.
WhatsApp will prompt you to restore your chat history from the backup.
To restore from an iCloud backup:
Uninstall and reinstall WhatsApp.
Verify your phone number and Apple ID.
Tap "Restore Chat History" when prompted.
5. Contacting WhatsApp Support:
If you've tried all the above steps and still can't recover your messages, you can contact WhatsApp support for further assistance
