Founders serving African markets — are you sure customer drop-off means "no demand"?

If you sell SaaS, courses, or subscriptions and you've seen low conversion or churn from customers in Nigeria or elsewhere in Africa, I'm curious about something.
Most founders read this as "the market doesn't want it" and move on. But there are at least two very different things that can look identical in your analytics:
Customers genuinely don't want your product
Customers want it, try to pay, and can't card declined, unfamiliar checkout, FX restrictions blocking the transaction entirely
These look the same in a dashboard. A drop-off is a drop-off. But they mean completely different things for your business one says "wrong market," the other says "broken checkout for a market that's actually interested."
I've been researching this and case 2 is more documented than most founders realize Nigerian banks have restricted international card transactions for Years,So the failure often isn't the customer changing their mind it's structural, and invisible, because nobody complains, they just quietly fail to convert.
If you've seen this pattern decent traffic from Nigeria/Africa but conversion that doesn't match I'd genuinely like to hear about it. Not pitching anything, just trying to understand how common this actually is and how founders are currently handling it (or not).
