When logging in to Skype using the Android App I get the unhelpful error message "Unable to sign in", followed by an even more unhelpful blank screen. The account is fine on the PC & IOS versions. I can login using another Skype account on the Android App.
I did some digging and found comments about clearing the cache etc. after a Force Stop. There is no cache clearing option to be had on my Samsung Galaxy S7 Edge running Android 7.0. Also it is impossible to uninstall Skype as it is embedded on this device, all you can do is remove updates, but you have to reinstall them before you can run Skype again.
I would appreciate any help that can be given.
Thanks!
