I have the latest Dropbox app on my 2011 MacBook, iPhone 6S and iPad 9.7 2017. iPhone and iPad are on iOS 12.1.1. All devices are connected to the same WiFi network.
Everything works perfect on the Mac and iPhone. However, the iPad app will not open any file whatsoever. It just spins the little wheel and never loads.
I tried clearing the cache, reinstalling the app, and restarting the iPad. IT WILL NOT OPEN FILES. I can access the Dropbox files just fine through the iOS files app and through Safari on the iPad, but not the Dropbox app where I need them most.
