in newer version, I don't know how to change URL or get custom URL?
no plus ones
Peggy K: Hi +JD WEB TECH as far as I know, the eligibility requirements for a custom URL have not changed. You will just have to switch back to the Classic user interface to claim an offered URL.
That means that if you are using a Profile, your account must be at just 30 days old and have 10 followers. If you are using a Brand Account you must associate your website with the Google+ Page (also requiring you to switch back to Classic G+).
