Answer 1

Hi,
Did you use the same account with the App creator(the account which deployed the app)? You can use the app creator to check whether it works.
Could the other accounts access the apps? You can use the other accounts to check whether it works.
To quickly and accurately find the issue, you can check the event log and ULS log to see if anything unexpected occurred.
For SharePoint 2013, by default, ULS log is at
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS
Thanks & Regards,
Jason
