Missing Connect Button

Any help would be appreciated. When trying to port to a new device, I was not asked if I had an existing account, it just started a brand new game. I can't delete the new account, because everything I can find online is telling me to use the "Connect" button, but it is missing. I've tried uninstalling, clearing the cache then deleting the app, but nothing will clear out the brand new account on the new phone. EA help has been of zero assistance, with lots of wait times, and ineffectual staff who don't seem to understand the issue.
