Onboarding Friction for High-Volume Crypto Payments

Anyone else hitting a wall with KYB for crypto payment rails when dealing with truly high volume?

We're talking multiple weeks of back-and-forth, redundant document requests, and a general lack of understanding of complex corporate structures. What are the common bottlenecks you've encountered, specifically around scale and compliance, and have you found any PSPs that actually handle this well without treating you like a retail user?
