What happens to $MSFTB on ex-dividend day is the part nobody talks about

I held $MSFTB through an ex-dividend date last quarter. Curious what would happen. Turns out the token price dropped on schedule, right in line with how MSFT always adjusts down by roughly the dividend amount on that date. Nothing broke. But nothing showed up in my account either.

That's the detail worth sitting with. A real shareholder eats the same price drop, sure - but gets the dividend deposited to offset it. I got the drop without the offset. On paper that's a mechanical gap, not a scandal, but it's real money if you're holding size and not accounting for it.

I went back and checked how the custodian side actually works here. The underlying share is held 1:1, and the custodian does receive the dividend on that share. The open question -and I genuinely don't have a clean answer - is what happens to that cash afterward. Whether it's reflected anywhere for token holders, folded into the backing, or just sits with the custodian as a structural detail nobody advertises upfront.

I'm not assuming the worst here. I'm just saying this is exactly the kind of mechanic that matters if you're holding a dividend payer for months instead of trading it short-term. It changes the math on total return, not just price return. This is precisely the type of detail #bStocksCIS should be digging into more, instead of just comparing charts.

Has anyone confirmed directly how dividend cashflows get handled for $MSFTB or similar names? Would genuinely like to hear if @BinanceCIS has documentation on this, because I couldn't find a clear answer myself.
