Photo backup on iPhone isn’t working - alternating between files

My Camera Uploads stopped working in my Dropbox app on my iPhone yesterday. All it does is find the number of pictures to upload and run a neverending blue bar back and forth across the screen non-stop, but it does not upload anything. (Sometimes it'll alternate between one number and the number just below it, such as 60 - 59 - 60 - 59, etc. but nothing is actually happening.) I left the phone screen on and the app open for over an hour, and the phone was plugged in and fully charged. I have plenty of space in my Dropbox. I discovered that the app had updated itself yesterday and I think that is the cause of the trouble. (To be clear, I am talking about a Dropbox app update, not an iOS update.) I've checked my Wifi, restarted my device, all the things that the help documents tell you to try, with no success. It looks as though many others here are experiencing the same thing. I hope Dropbox can issue a new update that will fix these bugs, as I rely heavily on Camera Uploads to transfer my pictures.
