Prop Firm Payout Reliability and KYC Friction

Curious to hear others' experiences regarding payout consistency with various prop firms. I've been running through challenges with a couple of different outfits, and while the trading conditions are generally acceptable (spreads, commissions, etc.), the bottleneck often appears to be on the withdrawal side. Specifically, has anyone encountered significant and recurring delays beyond the stated processing times, or unexpected friction during KYB for payouts, even after initial account setup? My concern isn't just about speed, but the overall operational overhead of having to chase down funds or resubmit documentation for every withdrawal, which eats into actual trading time and mental capital. It makes scaling more complex than it needs to be.
