I have been using Dropbox to store photos from my iPhone for years. Every so often, I upload them from my phone camera by opening the app, touching the photo icon and the uploads begin. It is set to use wifi, not mobile data, but that is no different. Until October 6th ago. As far as I know, I did not do anything. Why I try, it says 'All Done for Now' and no photos after that date are uploaded.
I am using iOS 14.0.1 on an iPhone 8
Thanks in advance!
