Dragonback Assault bug

Mtg: Arena for PC
Version: 2026.60.20.13374.1294424

-- Give us the steps to reproduce the bug
Opponent has a Dragonback Assault on their battlefield. When my turn came, I played a land, and my opponent added a dragon token.

That is an illegal move. Word on the card says "Landfall - Whenever a land you control enters, create a 4/4 red dragon creature token with flying."

"You" means only you have that card on your battlefield. It should not effect to opponent if they played a land.
