if it is an address beginning bc1 you'll have to change the type of address being created.
i'd argue that if any website nowadays doesn't recognize an address type that was added more than 3.5 years ago that means they have not updated their system for that long and it is no longer safe to use such incompetent services and they should be avoided like a plague.
in other words instead of changing your address type you must change the site you are using.
