@Puipui96 CVS is not a linked store. In order to receive credit for Ibotta rebates, you have to scan and submit a paper receipt. So make sure that at the register you select “print” when asked how you would like your receipt. Stores with updated systems prompt for that after you pay.
If you only get digital receipts, go into your ExtraCare account and turn that off,
My store just started this week asking if I wanted a printed receipt. it took me a second to register what the cashier was asking before I remembered my offers and said YES Please.
