Is there an actual reason the feature was removed? Or did the devs get high and decide it would be funny to remove it? I see no reason to decouple the checkboxes and the new installation button, I really cannot think of any logical scenario where a reasonable person would remove it. I understand that this isnt a "bug" but it sure is a pointless nuisance that causes a lot of wasted time. 
In case the devs need some explaining as to why you would almost never need to have them separate... when you add a new version, it is very very likely you are adding that version so you can play it. You know what happens when you add a new version? its added to the versions list, where it is bound by the checkboxes, the same checkboxes that should bound the new installations tab. If you are planning on playing a new installation, you will already have the correct boxes ticked to add it in the new installation tab. In case you don't want to play, well you are still likely adding them for a reason, and tick marks shouldnt change this. 
At best this "feature" has no affect on the player (this is only the case if they are choosing the newest version), at worst it is a supreme nuisance that causes adding older versions to take multiple minutes

I just want an explanation, not a reference to a changelog that tells me what I already know.

Yeah, this has been a thing since beta (probably further back, but I haven't played earlier versions)

Can confirm 1.18.2 (and the most recent snapshot)

No, the visual glitches are entirely different. I have an old video that I took of it and I can create another with F3 screen on if needed (although it happens no matter what you do, as long as you move quickly and make a turn)

The bug in the provided issue shows stationary visual glitches, this is entirely based on the player moving causing chunks to unload.
also to note, the visual glitches are much more "orderly" and happen in a single direction in an arc, not in a bunch of random chunks not rendering. The chunks will render again, but just take a bit.

This bug still happens in the latest snapshot (22w11a)

This is a bedrock bug/technical issue so this should not be posted here

My discord is BiC#6921

as @Mega Charizard X said, please state your hardware (RAM, CPU) also try recording this happening with F3 up with OBS. if you want, I could add you on discord for faster communication as this is not particularly a bug with minecraft, but a bug/performance issue with your computer.

have you re-loaded the world? minecraft will sometimes not teleport ridable entities when the player dismounts. re-loading should fix this

Please classify this as a bedrock bug as it is such. People working on the java platform will not be able to help you with this.

Please classify this as a bedrock bug as it is in bedrock (PE) not Java (PC.) The bug is most likely because the IPad 4 is an old device and apple is $h!t and likes to make you buy newer devices by messing up the drivers.

Please classify this as "bedrock" as this is a bedrock bug not java

This is most likely the game having to re-render the chunks every time you turn your head, I'd say either turning down render distance or using optifine would fix this

mouse sensitivity

the number stays the same, but the game perceives it as double
