I have found a working solution for me!
I did a fresh install of whatsapp via APKMirror. Than installed Google Drive and logged in. Make sure Google Play Services is installed and you gave the permission to: "Contacts, Music and Audio, Network, Notifications, Phone, Photos and Videos, Sensors and SMS." **Note: I am not sure if all of these permissions are necessary but this was working for me **
