I have two phones.
On one of them(PhoneA) I did a backup of WhatsApp data to a google account.
On another(PhoneB) I did a backup of WhatsApp data to a different google account.
And as a test, I have a google drive account with both backups.
If I uninstall WhatsApp on phoneB, and reinstall WhatsApp, it asks me if I want to restore the backup... It only offers me the backup of phoneB. But I want to restore the WhatsApp backup from PhoneA to PhoneB.
How can I do that?
