KYB in LatAm - dealing with beneficial ownership documentation challenges

Curious how others are handling KYB documentation, specifically around beneficial ownership, for entities operating in certain LatAm jurisdictions. We're finding it consistently challenging to obtain standardized, verifiable documentation from some smaller businesses. It's not necessarily a red flag in itself, more of a systemic issue with local record-keeping and company structure complexity. Are folks seeing similar hurdles? Any specific strategies or vendors that have proven effective in streamlining this without unduly increasing risk appetite?
