I am trying to develop an attendance tracker in the power-app connected to SharePoint list (user, log in & log out time).

since the user would be updating the app twice( once during login & another during log out), 2 different list are created. cannot find a way to combine in one list. can someone help?

login function - Patch('Online Attendance',Defaults('Online Attendance'),{'Log in':Text(Now(),DateTimeFormat.ShortDateTime)}

logout function - Patch('Online Attendance',Defaults('Online Attendance'),{'Log out':Text(Now(),DateTimeFormat.ShortDateTime)}

Hi @v-xiaochen-msft ,
There is an issue, suppose I "log in" via app & then I close the app, later when I reopen the app & try to use "log out" button the SharePoint list doesn't update.
but if I use log in & log out at the same time (without closing the app), the list is updated perfectly.
i guess the app deletes the variable we created, once we close the app. any other way of doing this?
