Ever since updating to 1.19.20, it is impossible to download new resource packs or update current ones from the Switch Bedrock Marketplace. It is possible to purchase new ones and browse the store, however.

Upon clicking 'download' or 'update', it initially does as expected. The progress bar gets about 1/6th of the way filled before an error message occurs. 'Something Went Wrong; We're having trouble connecting to the Marketplace right now. Please try again later!'

It continues to attempt to download after the error message, similarly getting 1/6th of the way through the bar and resetting once it reaches that point. It does this cycle 2 to 3 times total before the download button shows up again. Upon clicking it, the error message pops up again and it downloads in the background, does the 1/6th cycle, rinse, repeat.

I've reset my switch, restarted the console, checked my internet and router, checked my dns, and nothing seems to fix this. It's worth noting that this did not occur before the 1.19.20 update.

Steps on recreation: 

1. Download or Update a skinpack, texture pack, resource pack, or mash-up pack
2. Watch it not download.
