I have never been able to sign in to Skype bc I never knew what my password was for the app on my iPad. Whenever I request a pass code from Skype and copy/paste it it tells me the code is unrecognized. When Skype sends me the email with my passcode the link in the email shows a 4001 error. I have wifi in my home but cannot log into Skype to use it. Please help.
