ARROW OWNER DATA MODIFY NO WORK. PLZ HELP KTHX

You said Owner NBT is fixed for entities (works even after a certain period of time).

well, data modifying an arrow's OwnerUUIDLeast/Most and setting it from a player's UUIDLeast/Most doesn't work. (for summoned arrows)

Please, I need help in this. My datapack requires this

I'm pretty sure it's related to it not working after a certain period of time since arrows take 1200 ticks to despawn as far as I've seen.
