I give instacart shopper app one star. I am an instacart full service shopper. It is unfair customer's get 24 hours to adjust their tips because once the job is accepted by us based on the tip and we deliver, the job is done. I am expecting to get paid what I swiped for. Instacart I'm sure plenty of shoppers agree that you should change this back to 30mins because when the job is done, it is "done". I think changing this will also help with tip baiters that forget and remember later.
