Profile availability is opposite

If a person enters dates they are unavailabile, in their profile when selecting the “Available” tab the unavailable dates are shown. This is at least the case for the iOS app.

On the web version, the tab is called "Unavailable Dates," but it was shortened to "Availability" to fit better on mobile screens
The tab will show which dates the user has marked as unavailable. All other dates can be assumed as available
