I'm trying to broadcast a Taproot transaction to random nodes across the network (Testnet3).
When I try to broadcast to older nodes like 0.18.0, I get the error "Witness version reserved for soft-fork upgrades".
How am I supposed to broadcast a Taproot transaction to older nodes when they won't accept it?
Here is the raw transaction I'm trying to broadcast (it's a very simple single-sig P2TR spend):
(Keep in mind it might be broadcasted by the time anyone reads this as newer nodes do accept it.)
