My problem is that around half way through restoration, it says it failed, "Unable to restore whatsapp backup from google drive. Do you want to restore your chats from older backup?" So I chose yes, and it proceeded to backup, however it reaches ***, stalls and then says error and proceeds to continue without giving me an option to restore again, and all my chats are gone. *I understand you dont have any data regarding my chats, but please do tell me if there's any other way to restore chats, like via a computer manually? *Ive also tried renaming the backup, then making copies of the backup with different numbers, and deleting my google drive backup and using only the local backup, but I always end up with it just proceeding to regular whatsapp without a chance to backup again. *Your help would be greatly appreciated
