Hi all,
I'm have an app that tracks when employees request to use their sick/vacation time. Another coworker and I can each use the app no problem, and it reads and writes as it needs to. The problem is, we have one user who always gets this error when he opens the app:
"The Specified record was not found. Server Response: Vacation_Holiday failed: Error from token exchange: The connection (europe-002/sharepointonline/432021f58ce3460e96c78695ba926c80) is not found. Please create new connection and change your application to use the new connection."
I have tried editing our sharepoint list titled "Vacation_Holiday" and refreshing the connections in the app, but he still can't get the access he needs. In addition to seeing the error, two drop downs are blank for him, while for myself and others we see a list of employees. I'll include some images.
Does anyone have any idea what is going wrong?


I haven't selected the dropdown because it contains names of our employees, but it works for me.
