If you've had a change of heart and would like to resume your membership manually before the selected end date, just head to the membership pack page and resume it. Your membership will automatically be extended by the number of paused calendar days.
eg: if you chose to pause your membership from Jan 1st to Jan 10th, but decided to resume it on Jan 6th at 8:00pm, your membership will resume immediately but your membership end date will be extended by 4 days as your membership was paused only for 4 full calendar days.
You can even choose to cancel the Pause before midnight of the start date and your pause days/membership days will not be affected.
