After the 1.17.30 update on Nintendo Switch, cached items from servers now delete after you close the game making me have to re-download them every time I join a server. They used to appear and stay downloaded on 1.17.10. 

I checked it on my Playstation 4 and all downloaded data is still there so it seems to only affect the Nintendo Switch. 

Steps to reproduce:

1. Get another player to startup a world with texture packs enabled.
2. Join the other players world
3. Install the packs when asked
4. Leave the world 

Observed Results:

1. No items in cached data part of the settings menu
2. Joining the world again asks you to download the texture packs

       This bug also causes unreliable loading times and can cause the "Connection Timed Out" screen to show up multiple times before getting to the Texture Pack Download Screen

Expected Results:

1. Packs should stay after leaving the world so you can join the world quickly (all other devices do this)
