I'm a very new user of BC, just installed PC (Win10) and Android (6.1) versions. Desktop
version works flawlessly (passed my first test and use of encrypted files) but I can't use Android version. After log-in the app prompts me to add a provider but when I pick (any of them) I can see only a glimpse with "Loading" pop-up, it disappears and nothing else happens. Provider is still not added.
I tried to log-out and -in, clear cache, reinstall the app - nothing helps. Any clues ? Any help very appreciated... :-)
Update: not all providers behaves in such a inpolite way. With some of them I get regular login screen. I'm interested in Dropbox which acts as described above (OneDrive, GoogleDrive too).
