Plans: Pro, Agency and Enterprise (or an active trial)
Steps
Drag the middle of a bar to move it; drag either end to change the start or finish date.
Tasks that wait on the one you moved shift by the same amount.
If you drag a task earlier than a task it waits on, a small window explains the link. Choose Keep my dates to save your dates and pause that link (it comes back automatically once the dates fit again), Edit links to change it yourself, or Cancel.
Every date change shows an Undo option for a few seconds.
Rules and limits
The Schedule page is included from Pro upward. Starter and Free plans see an upgrade prompt instead of the calendar.
WinkScope AI only plans work the scope implies; it does not add extra trades or prices, and its dates are suggestions the user should review.
The AI plan is added only after the user clicks Add to Gantt.
What this cannot do
Pull in dates from Google Calendar to build the plan.
Drag sub-task rows that live inside a task directly; open the parent task to edit them.

If a step does not match what you see on screen, stop there and open a ticket from Support > My Tickets with a screenshot of that step. The team will look at the account directly.
