Hi!
I’m in the progress of changing my email account, and when logging in i accidentally pressed “Log in with Google” on my smartphone and that created an new account for my new email address.
When i discovered my fault i deleted the account connected to my new address, but now i still cant change my email on my previous account to the new one (“EMAIL HAS ALREADY BEEN TAKEN”). Is there any more steps needed to free the address used on my accidental account so i can link it to my real account?
also a side note, the link in the forum welcome message: “Welcome to our forums! Please take a few moments to read through our Community Guidelines (also conveniently linked in the header at the top of each page). There, you’ll find guidelines on conduct, tips on getting the help you may be searching for, and more!” points to https://support.plex.tv/hc/articles/220049328 that renders a 404 error. 
cheers,
Runar
