Shareable boards (available on Standard plans):
Are ONLY accessible by those the board is shared with either INSIDE your organisation or OUTSIDE your organisation.
Private boards (available only on PRO plans):
Are ONLY accessible by those the board is shared with INSIDE your organisation.
I don’t understand why shareable boards would be available on the cheaper tier? What’s the point in having a private board when shareable boards do everything private boards do but also allow you to invite someone from outside the organisation?
Am I missing something?
