How long do I have to undo a post?

After you tap Post, your shift waits a few seconds with Undo before it goes live. Tap Undo in that time and nothing is sent, held or charged.

You choose how long it waits: 5, 10, 15, 30 or 60 seconds. It starts at 5. Turn it off and a shift goes live as soon as you tap Post. Change it in Profile, then Security, then Undo payments.

It’s your own setting, so it follows you to any phone or tablet you sign in on. It never skips a check that it’s you.
