On PowerApps studio for Web, seems that the sample app Invoice Management works fine.
On PowerApps studio for Windows, when creating an app from the template Invoice Management, I get an error message saying that “The requested operation is invalid”, and there is no data shown on the app.
What’s the error message on your side? Could you show me a screenshot of the error message? I will be going to collect and report this issue on my side.
Best regards, Mabel Mao
