Cloud Storage that's accessible via the Kindle's browser?

[hleo12]

I don't wanna necrobump a 3 year old thread, so I'll just link it here

But as the title suggests. Are there any cloud storages that works with the Kindle's browser?

The old thread said box.com still works (at the time of the post), but box seems to be having some problems here. I can't access it even on my pc browser, and according to their support on twitter, they have received reports that users in my country can't access their site.

I tried amazon drive/cloud, but I got a notice that their services will stop next year and will be transferred over to amazon photos. Sadly, amazon photos doesn't load using the Kindle's browser.

Are there any other known cloud storage services that works with the Kindle's browser?

Or is the Kindle's browser so far behind it can't support any of the newer website UIs?
