Running iOS 17.3, just updated.
When I try to share content to Dropbox, I get an error message: “Couldn’t save content. Check your internet connection and refresh the page. There’s not internet connection issue; I’m connected. This is Dropbox-specific. If I use share to Save to Dropbox, that works fine; no error. This also seems unique to the latest iOS update, as I didn’t encounter it before that. I tried uninstalling and re-installing Dropbox, and simply re-starting. Neither helps.
