Anyone else finding prop firm withdrawal processes needlessly opaque?

It's beyond frustrating when a prop firm's payout terms are deliberately vague, especially around the initial withdrawal. We're talking about basic operational stuff here – what's the actual processing time, what specific documentation beyond the KYC I already did do they need for the first payout? The whole 'up to 10 business days' line feels like a cop-out for something that should be a standard, clear-cut banking transfer. Is this just par for the course now, or am I missing firms that actually streamline this?
