I'm on an iPhone 7 running the latest iOS and my world is 150mB. Before, it ran just fine, but after updating to 1.19, the game slowed down dramatically. Here are the issues I've noticed:
Chunks no longer load fast enough to glide with the elytra. Oftentimes the player will hit the wall of a chunk and will be unable to go further until the game catches up
It takes a good minute for the world to load when crossing portals
Block lag is extreme; blocks reappear after the player broke them
Entities move/take damage slowly (may be result of slow tickspeed)
Opening inventories (chests, furnaces, etc) take a while
When arriving on other side of Nether portals, the game will rubberband the player back to the portal if they have moved out of the portal
Overall, the gameplay has become more stutter-y. There are also moments while walking around where there is a sudden lag spike, and the game freezes for a second or two. Originally I thought this was due to old hardware or little storage available, but I see many others are experiencing this issue on newer devices. If this could be fixed with 1.19.10 that would be great. I'm sure Mojang is actively trying to analyze the cause of this and fix it.
I have over 2 GB of space available in my MinecraftWorlds folder and my survival world is about 127 MB. However, it fails to create a copy. This isn't really the end of the world since I can duplicate the world folder in my files, but it would be way more convenient if I could copy the world directly from the game to make backups.
Also, on a copy of my survival world, I messed around in game and made the world size larger but I was able to copy it but not the original world. (Eventually deleted the copy because it was me testing stuff in creative)
If anyone knows what could be wrong or how to fix it, please tell me, I'd appreciate it.
This only appears to happen when I’m in creative mode
I have this problem as well and I don't know why it keeps happening. It appears to be for one specific gateway only.

The bug has been fixed as of 1.19.63. Thanks!
