I'm trying to set up a community. There are certain things I can only do on a computer or Reddit.com. When I log into the app from my phone the email i use pulls up the account name I should be using. When I go to the website, it's a fifteenth account. Same email address, but doesn't handle and username. It's it me? How do I fix it or delete the one without deleting the other? Both show created on the same day.
