How long does this usually take

I sent out my first FBA shipment last week for one of my high demand PL products. It’s a small item and I shipped in 100 units, fully packed, labeled with the fnsku and suffocation warning. Basically, I sent in my entire stock. I’d been handling everything myself with FBM and sales were going well, but the demand was getting too much so I figured it was time to switch.

I was a little nervous about it since I’ve seen people post about fulfillment centers losing whole packages. Just wondering how long it usually takes for Amazon to process the units once they arrive.

The package was delivered to the fulfillment center on May 23rd. And the status still says delivered.
