KYB headaches with new offshore PSP for corporate accounts

Anyone else hitting major friction lately with KYC/KYB for corporate accounts, particularly with PSPs based in smaller jurisdictions? We're trying to onboard a new payment solution for a few European entities, targeting one based out of Mauritius for its specific fiat on-ramp capabilities. The onboarding process feels like a black hole – endless requests for documentation, often duplicate, and then weeks of silence. We've provided audited financials, UBO details, proof of address for every director, and still, the goalposts keep shifting. It's impacting our operational efficiency significantly. Are there any specific red flags or common pitfalls that trigger this level of scrutiny, or is this just the new norm for non-Tier 1 PSPs when dealing with EU corporate clients? I'm open to suggestions if someone has navigated this successfully without excessive delays.
