My Dropbox says, your Dropbox is outdated but in the App Store there is no update available to download. When I click the words which are in a red box on my iPad it takes me to the store but it just shows a button with open instead of update.
Does your iPad meet the minimum requirements for Dropbox? If it's an older ipad and isn't running iOS 11, then you won't be able to install the latest version of the Dropbox app. Older versions of the app are not supported and will eventually be prevented from connecting to Dropbox.
How do you get refocussed while working from home? Do you find any of these options keep you from getting distracted?
