The email address I used the very first time I tried to use Opera is not the email address attached to my everyday log in credentials. I could never figure out how to locate or access the original account again after initial set-up, so I started over using a different email address that I've used to gain access with regularly, ever since. The problem is that whenever I try to use that other email address for regular business purposes, Opera refuses to accept it stating that it is being used by another Opera account. How do I find that unused second account and separate it from the platform?
