WhatsApp iCloud Backup Restore Not Showing on iPhone

Hello,

I am trying to recover my WhatsApp chat history on my iPhone. My iCloud backup is enabled and shows the latest backup, but when I reinstall WhatsApp, it does not give me the option to restore from iCloud backup.

End-to-End Encrypted Backup was enabled.

iCloud Drive is ON. WhatsApp iCloud storage also shows data.

But restore option is missing during reinstallation.

Please guide me on how I can recover my WhatsApp chats.

Device: iPhone 15 Pro

iOS Version:26.0
