I built a power app which connects to a sharepoint site using a service account.
A colleague of mine built another app and it won't allow me to connect to the share point data source complaining about permissions, we worked out that it's using the service account to authenticate. When we add the service account to the site permissions it works fine.
What is really strange is that even when I open the app in an incognito browser and provide my own login credentials it still fails.
It's only me in the organisation that has this issue and it's also only me in the organisation that has been working with power apps.
I definitely have access to the share point list as I can connect to it directly
Please help
