I have deployed my hosted app in test site environment with version 18.104.22.168 In the same version I have one list named Employee. Now I renamed the list name as Employees raise the version 22.214.171.124 and updated the app in same test site environment. The issue now I am facing is that in updated app there are two lists present named Employee and Employees. I don't understand why this is happening. Suggest some help.
Your App/Addin upgrade won't wipe out any app web content, that's reason why you still see the Employee list. You might need to retract the app and install again if you want a fresh start on app web contents.
