On a monthly plan you can take a month off instead of cancelling. The pause sits inside the cancel flow, so that's where you start.
Open Settings → Plan & billing and choose Cancel plan.
On Before you go, pick I’m not using it enough and choose Continue. That's the reason that offers the pause.
On the pause offer, choose Pause for a month.
When it worked, a Pause scheduled message confirms the dates, and Plan & billing shows when your plan pauses.
Before the pause starts
Nothing changes yet. You keep your plan and its monthly usage until the end of the billing period you've paid for, and the pause starts on that date. Nothing is charged to schedule it.
If you change your mind, choose Keep my plan on Plan & billing, and your plan renews as normal with no charge until then.
While it's paused
There's no monthly usage and no plan features.
Your Series don't post, nothing publishes, and you can't change plans.
If you have usage packs, you can still make and download videos with them.
Nothing is deleted. Your Library, your Series and your settings stay as you left them.
Coming back
After the month, your plan starts again on its own and billing resumes. To come back sooner:
Choose Resume plan at Settings → Plan & billing.
Check the amount, then choose Resume and pay.
Resuming charges your monthly plan price straight away and starts a new month with fresh monthly usage.
If you see Your card didn’t go through, the charge failed, so nothing was charged and your plan is still paused. Update your payment method, then resume again.
The pause is only offered on an active monthly plan. If a month off isn't enough, Cancel your plan covers what ends and what stays.
