I’ve been playing Duos on my iPad Gen 9 and I have noticeable desync issues. It seems like the animations are just a little bit slower and that accumulates to a lot of desync. The problem is that I end up missing out on time in the tavern and have had times when I loaded into the rope already going. If high APM builds like pirates weren’t already hard enough on a tablet missing out on significant portions of your tavern time makes them unplayable.
I’m playing in the same room with my son and so I can see almost immediately things start getting out of sync. It’s especially bad when you have things with lots of animations like the new Beast stats when taking damage build. My son’s computer is pretty old and slow but still easily ends up ahead of my iPad in combat.
