My phone had a problem so the mobile repairing center did factory reset. Then I reinstalled whatsapp and tried to restore backup from Google Drive. It took about 1:30 hours for 400 Mb and didn't show any indicator for what percentage it has completed. So I just tapped home screen and then tapped whatsapp. It showed me a new window of entering my username and took me to chat window. There I saw no previous chats were present, just 2 old groups and also no messages in them. I again Uninstall and reinstall whatsapp it didn't show me 420 Mb data size, it asked me if I want to recover today's messages. Can you please tell me can I get my backup from Google Drive again?
