KYB/Onboarding Friction with PSPs for High-Volume FX

Anyone else finding the Know Your Business (KYB) process with payment service providers (PSPs) for larger FX flows increasingly cumbersome? Seems like every year the documentation requirements escalate, especially around UBOs and source of funds, even for established entities with clean records. It's creating significant delays in getting new merchant accounts stood up, directly impacting time-to-market for new strategies. Curious if others are experiencing similar friction and if any workarounds or specific PSPs are proving more efficient for high-volume, low-margin FX operations.
