How to clear the Dropbox mobile app cache on iPhone/iPad?

[Marcus D.9]

Using an iPhone 5C running iOS 9.1 and Dropbox 4.0.4. The iOS Dropbox app itself is only 55.8 MB in size, however my iPhone is reporting that Dropbox is using a total of 300+ MB in Documents and Data. I have zero files marked as "Offline" within the Dropbox app, so the app should not be storing any Documents or Data locally on my iPhone.

I realize the Documents and Data referenced are most likely the result of recent files being cached by the app, but if this is the case, is there any way to manually clear that cache? Or set a limit of cache size? Currently, uninstalling and reinstalling the app is the only solution I've found, which is far from what I'd consider a "solution". I have to uninstall the app, reinstall it, sign in, wait for 2-factor auth code to enter, set up my Passcode again, set up the Camera Upload again...just a horrible overall process just to clear out the cache.

There are other apps which allow you to either set a cache size, or some that include an option to manually clear the cache. Either one of these options would be better than nothing at all.

I actually have a number of apps installed with manual control over clearing the cache. One of them is just a simple wallpaper-downloading app, which has complete control on the cache, including the ability to set a max cache size or clear it altogether. Can't be too terribly difficult for Dropbox to figure out if these other apps have.

My Dropbox app on iOS is taking up over 15 GB of storage while I have no offline files there. And Dropbox still has the nerve to tell me "To continue using Dropbox, delete some files, photos, or apps from your device." while it's Dropbox itself that is causing the problem. AFAIK there's no way to clear the cached data except for reinstalling the whole app. Please fix this issue.

I'm seeing the same problem, it just keeps growing and now I have to uninstall just to get the room back... Tumblr had a similar problem but they added a manual way to remove the cache. This need to be addressed, Dropbox.

Having the same issue... Signing out and back in seems  to deflate the size... It starts growing again once I start browsing but it's less of a pain than uninstalling and reinstalling the app. A Clear Cache button would be great, just like there is one for Clear Recent Searches.

... So..? Just nothing?

+1 for this please, Dropbox is using a huge amount of my iPhone's storage needlessly and I've had to remove the app and go through the whole setup process again.

Tempted to dump the iPhone anyway and get an S7 as I'll be due for upgrade soon, I'm sure it's easier to clear the cache on Android?

So...signing off will do the trick. 

I guess that is good enough solution for now, my co-worker keeps deleting files from shared folders, all in attempt to free up space in his phone.

In the meanwhile I will be recovering all of the deleted images.

Signing out and in again cleared my 1gb cache. It's quite fast so it can be done regularly.

Caveats: your offline files will be lost and you'll get an annoying "a new phone has been connected" email.

Signing out & signing back in did not clear my cache, I had to uninstall & reinstall.  Please respond to this thread, Dropbox, you are a great service in so many ways but this is really poor & quite crippling to those of us saddled with 16gb phones.
