slot provider review after a big win taking 14 business days, is that normal

So I hit a pretty decent jackpot on one of my favorite slots a couple weeks back, and the provider told me it’d be up to 14 business days to process the payout. I know some folks here have had much faster turnarounds, but I’m curious if anyone else has been asked to wait that long after a decent sized win? This is the first time for me getting told it’d be such a slow payout, even though I’m used to sticking with the calmer, more reliable providers over the years.

My docs are all in and the casino verified me ages ago, so there shouldn't be anything weird holding it up. Kinda takes the shine off the win a bit, having to wait and keep checking my account every day. Has anyone else had this experience and did it end up coming through on time?
