Okay, I just wanted to come back here to clarify something in case my issue on NSwitch has led to unnecessary confusion.

I had stated that I was having problems in new worlds and old worlds and in exploring new areas, so let me elaborate on that a bit.

In new worlds, I was only exploring new chunks to fill in the maps. I can also say that I was only exploring new areas in existing worlds to fill in maps, (specifically level 4 maps). I did not notice anything other than chunk-loading lag and occasional freezing (required waiting a moment or two so the game could catch up)  while doing so. But it did take me over an hour to finish one map, doing nothing else but flying through on creative (and the fast flying wasn't working).

The block-breaking and placing issues were experienced in existing worlds without traveling far away and in Marketplace worlds (FarmCraft and Jurassic World ones, had major problems, to name a couple specifics).

I don't recall if anyone else stated they had issues in new worlds and in areas far enough away other than myself, but I don't want to be the cause of throwing the team off the right trail. 

I wanted to add that Auto-Save has been happening WAY too often, and it's during the auto-saves that map loading lags the most!

@Brandon Cyr - I hadn't noticed the auto-save problem specifically before the update, but map-making has definitely been getting slower over the past few updates, so perhaps I just never connected the auto-save issue to it. But currently, if auto-save coincides with attempting to load a new chunk, I will attempt to move my character and nothing will happen. It looks like my character is moving (changing direction, walking animation, etc) but the coordinates don't change, the world around me doesn't load at all, the map doesn't generate, so for all intents and purposes the world is frozen for a minute or two.

I've been attempting to work on my world again today. As some background info, this world was started just a week before the update, with not too much done - just a couple of simple stone houses, a simple farm (wheat, potatoes, carrots...), and mainly gathering resources on survival/peaceful. A couple of days before the update, I copied the world to switch the copy to creative mode to make a couple of Lv. 4 maps to get a general idea of the seed's landscape without needlessly loading in chunks in the main world (as save space has historically been an issue for Minecraft on NSwitch).

It only took me an hour and a half to finish one Lv. 4 map today /s... 😞 Now on to see how things are running back on survival!

Can I second Sheridan's request for a rollback?? And I echo the sentiment of just wanting to minecraft and chill. (Sheridan, you got me rolling with that last sentence!)

And is there anything we console Bedrock players can do to help aside from overwhelming you all with reports like these?

Playing on Nintendo Switch and also having similar issues. Is anyone else having problems with mapping on top of it all? The chunk loading lags so badly (especially while auto save is happening) that where flying in creative mode to generate the world and complete Lv. 4 maps used to be a great convenience, it is now a major hassle. It takes ages to complete Lv. 4 maps now... 

Edit:

Also of note (for NSwitch players, at least) the problems persist in worlds downloaded from the Marketplace as well.

Additional edit:

Just to clarify, the lagging occurs on NSwitch in single-player, multi-player, online, offline, new worlds, old worlds, small worlds, and large worlds all the same for my son and I, both using our own consoles. It seems to be worse during auto-save, but still occurs when not auto-saving. Also, does it seem to be auto-saving a lot more frequently to anyone else, or is that my imagination?
