Onboarding Friction with PSPs for High-Volume FX

Curious if anyone else has faced significant hurdles with PSP onboarding lately, particularly for anything beyond standard e-commerce. We're running into a wall with KYC/KYB on volume for FX-related transactions, even with all documents in order. The processing times are killing potential deal flow, and some providers are just ghosting after initial contact. It feels like the compliance burden has ramped up considerably, making it tough to even get to the stage of discussing spreads or liquidity, let alone reliable payout schedules. Any strategies for streamlining this or specific red flags to watch out for with providers that cause these delays?
