Hi,
In my project, I had no login screen initially. Only forms were there. Based on forms filled, we were updating the response of form in another sharepoint list1.In this list, we were updating user name by ThisItem.'Created By'.DisplayName. This list was updating O365 user of powerapp.
Now instead of updating the sharepoint list 1 response sheet with O365 powerapp user name, we want to update with user created in login screen.
I have created a login screen from one sharepoint list2 having list of users and password.
I want to update these user names from login screen to sharepoint list1.
Please help.
