apple card and restaurant tips

Hello. I recently used my Apple Card (titanium card) at a restaurant to pay a large group bill. I added the tip when presented with the bill. I don't see the whole amount listed on my card in my wallet, so does that mean the waiter didn't receive my tip? (ugh, I hope that isn't what happened...I'll never return)

How does this work? Should I have left 'cash' for the tip? Any information given will be appreciated.

Thank you...

Linda
