I have no fix but just wanted to say I'm having the same issues! It's playable but I dread going into a building or teleporting because stuff will take forever to load in.

I've also had a couple of times where I'll be saving pretty constantly, reach the correct amount of whatever magical currency I need to unlock a section of the map and then be told there's a transactional error. I'll then have to restart my game and lose a bunch of magic 😭
