Anyone else hitting a wall with KYB/onboarding for new prop firms focused on commodities?

Been looking at expanding my exposure into some less liquid commodities recently, specifically some agricultural futures that aren't on my main broker's book, or if they are, the margins are just ridiculous. Found a couple of prop firms advertising access and better leverage/margins for this stuff, which is great on paper.

Problem is, the onboarding process has been an absolute nightmare. It's like they've never dealt with a professional trader before. The KYB requirements are scattershot – some asking for bank statements from five years ago, others rejecting perfectly valid utility bills for no clear reason. And the timeframes? I'm talking weeks, sometimes over a month, just to get past the initial checks, only for them to come back and ask for more 'clarification' on something utterly trivial. It's severely impacting my ability to react to market shifts when I'm waiting this long to get capital deployed.

Is this just the new normal, or am I hitting a bad patch of operators? How are others managing to get set up efficiently with these newer or more niche platforms, especially for commodities where timing is often everything? My main broker has been solid for years, but their scope for certain commodities is limited.
