Minecraft Switch chunk loading, lag, and FPS issues

Hello!

Minecraft on the Switch (digital version) has been experiencing bad FPS, loading times, access to the marketplace, and chunk rendering. I've had this problem for a long time, but I typically try to grin and bear it. However, every new update makes it more unplayable on the Switch. I can't walk anywhere without large missing sections. Almost five minites in, everything slows down tremendously. I've never been able to get the marketplace to work too. I don't think I need that, but it was worth mentioning that it never works. For that matter, the skins don't work either.

Since reporting this issue in the last week, I have been bounced around by Minecraft customer support. They sent me to Nintendo and now here. From a customer service background, I am just getting the run-around. I don't feel like it is the Switch; none of my other games have these issues when docked, it is just Minecraft (ironically, Minecraft Dungeons gives me issues too, but not as bad as classic Minecraft). 

I have taken the previous advice from this site, Reddit, and several customer support agents over the years. Here is everything I have tried:

• I contacted Nintendo per the request of Minecraft customer support, Nintendo customer support said, "we don't have any troubleshooting steps available for this type of issue that is related to the game itself. The developer has to provide you with any other troubleshooting or additional steps in order to find a solution for this issue."

• I fully restarted my console from the power options in settings and selected and launched Minecraft without opening other games or apps. 

• I tried not signing into a Microsoft account (I wish I didn't need to anyway). Honestly, I feel like this option makes it worse. Minecraft is constantly trying to connect to something, which tanks the game performance for me. I also lose the ability to switch skins (even the ability to switch between Steve and Alex). 

• I deleted all of my worlds (which hurt the most) and started fresh. This solution helps until the world reaches about 30MB.

• I dropped all of my settings to the most optimized and least demanding.

I am attaching screenshots of the issues. Some I could not capture with a screenshot (how do you screenshot low FPS/ lag, issues with skins, items not appearing, or loading times?), but I did capture the chunks not loading in and my settings. If I can send other images to help troubleshoot let me know. 

Is there something I can do or download to improve the FPS? Is there a free texture pack on the Switch that can help with FPS similar to the PC version? Can I create a smaller world? Maybe scale back the updates? I am open to anything at this point as I would rather play the game than have it be so slow.

If there are any options, please let me know! I feel like Minecraft on the Switch has been unplayable since I got it three years ago, and it is just getting worse. There must be some solution now.

Thank you for your help!
