Project description:
"I recently switched phone numbers and completed WhatsApp’s built-in “Change Number” process, but my old chats never made the jump. I can still open WhatsApp on the new SIM and send messages, yet the entire message history tied to the previous number is missing.

Here’s what I need from you:

• Pinpoint why the transfer failed after I followed the official steps.
• Guide me—via concise written steps or a quick remote session—through a reliable method to move every chat, media file, and group setting from the old number to the new one.
• Make sure future backups (Google Drive / iCloud, whichever you recommend for this fix) run smoothly so I don’t lose anything again.

If specialized software, command-line tools, or cloud-backup workarounds are required, please outline them clearly before we begin. I’m ready to provide any logs, backup files, or device details you need for a successful recovery." (client-provided description)
