Change email account

Hello,

I used plex for several years. The account I’ve created years ago is linked to an email I no longer access.
I’d like to change the email in the settings, but it says that my nowadays email is aldready used.
What can I do ?

If it says the new email address is in use, then there is another Plex account which uses this email address.
You need to delete it (this “new” account!), then wait a month and after this waiting period you should be able to switch the email address on your “old” account.
