Marketplace purchases stuck on downloading

There are multiple items that I have purchased on the Minecraft marketplace, and a number of these items have been stuck with a download bar. I was able to play them previously but now they are unplayable. The most common of the types of purchases that won't work are the ones with worlds attached. I think this issue might have already been reported, but I thought that I might report it too. I really hope this gets resolved as I have used my own money on a few of the items. Thank you.

p.s I have put an example picture
