When you have an active Team subscription or a trial Team workspace, you’ll only see the option to upgrade to the Team plan on your Team admin page. If you’d like to use the individual Pro plan instead, you’ll first need to cancel your active / trial team workspace (this can be done by your team admins in the Account & Billing section of your Team account settings).

Once your Team has been cancelled, you can continue to upgrade to the Pro plan in the subscription section of your account page.
