Error re: requiring immediate payment

Intermittently and for no apparent reason, I sometimes get an error in GarageSale (7.0 Beta 34 (754) that says:

“If this item sells by a Best Offer, you will not be able to require immediate payment.”

I’ve no clue what this means, or what causes it, either by pattern or logic.

Can you shed any light on this?

Maybe BUY IT NOW requires immediate payment, but BEST OFFER added to that doesn’t? Are you getting it on BIN without BO?

All of my BIN listings include Best Offer, and most of them work perfectly, so that’s not it.

Could it be that it’s just a warning/ info message from eBay?
Maybe immediate payment is not possible if someone places a best offer (that you need to accept)? Just a guess.

No. It pops up randomly. I always use OBO, so it’s not that.

If I upload it as-is a second time, it goes through. Just wastes a lot of time.
