I found a doordash free food glitch

So apparently to this tiktok post if you go to cashapp and wait on the confirmation screen then go back to doordash and click submit order then wait 2-3 Seconds then swipe back up to cashapp and withdraw the savings by clicking through the confirmation then it glitches it by letting you complete the order but then saying you have insufficient funds.

P.S: I feel bad for anyone who uses this method because once doordash finds out they are cooked
