Help! My instant advance shows as "delivered" but my balance hasn't updated?

I used the instant transfer feature on my finance app about an hour ago to cover a grocery run. The app says the transaction is complete and the fee was deducted, but my actual checking account balance is still showing $4.12. Usually, it's instant (hence the name). Has anyone else experienced a lag like this on a Sunday? I’m standing in the checkout line nervously sweating.

Don't panic yet! Even instant transfers can snag on the backend networks (like Visa Direct or MasterCard Send) during high-volume times. I’ve seen it take up to two hours on weekends. Just don't try to send it again or you’ll get hit with double fees and a potential overdraft.

I had this exact same issue a few weeks ago when I was trying to get gas for my DoorDash shift. It showed completed but the money was in limbo for almost four hours. I got so frustrated thinking I’d be stuck at the pump that I frantically started searching for the dave banking phone number https://dave-banking.pissedconsumer.com/customer-service.html, hoping to get a human to verify the transaction status manually. By the time I actually found a way to reach out, the money finally hit my account. It seems like Sunday afternoons are just notorious for banking lags, regardless of what the app promises.
