Hi guys! I searched the forum already, could find other users having the same issue as I do, but no solution. I had to restore my iPhone 6 from iOS 8.1 to iOS 9.3.5. I have a Whatsapp backup with chats and media, it's on iCloud. It's the backup from the app itself, the one you can set to happen automatically every month/week/day. I restored this backup, since the app asked as soon as I opened it on the new iOS. All chats are here, the media was downloaded (2.4 GB) but is just white placeholders. I contacted Whatsapp's support, they sent me a useless standardised email with a link to the Backup and Restore FAQs and didn't answer to my detailed reply anymore. Do you maybe have a solution to this problem? I don't want to believe I'm the only one having it! Thanks a lot!
