On my iPad Pro 11 Inch (2018), Minecraft Bedrock 1.19 is completely unplayable. I have experienced the following problems in the span of 3 days using 1.19:

Cannot open inventory for a few secs after going through nether portal. This period seems to last longer when on a Bedrock Dedicated Server (sometimes lasts 40 secs)

Chunks load way slower than before. Easiest way to reproduce this is to fly in a straight line with elytra.

Chunks sometimes fail to load completely without a game restart after going through a nether portal. I have only been able to reproduce this one in a Bedrock Dedicated Server

Invisible blocks are sometimes created in unloaded chunks, rather than just letting you fly through them like normal

Random death - This may be tied to the invisible blocks I talked about before, because this only happened to me once when I had been standing on some invisible blocks, then went back down to a normal chunk. I have not been able to reproduce this one, but when it happened, I was on a Bedrock Dedicated Server

Long delay when tying and sending chat commands for the first time since loading into that world

Sometimes you stop being able to shoot rockets to propel your elytra for long periods

I have not been able to reproduce any of these issues on the following newer devices:

Xbox Series S

iPad Pro 11 Inch (2021)

I have been able to reproduce it on these older devices, however:

iPad Pro 11 Inch (2018)

iPad Pro 12.9 Inch (2017)

at a time - Usually they do shoot about 30-60 secs after trying to shoot them, but just consume the item without propelling you. I have only been able to reproduce this one in a Bedrock Dedicated Server

Please vote for this issue so that Mojang will see it, as I would really like to explore the new update, but I simply cannot with these problems.
