We are not able to see the view in the SharePoint list when powerapps is created from powerapps portal. I have discussed this in detail in the forum.
This is by design. We don't actually automatically put an app into the SharePoint List views because it may not be desired by the App Maker. There are some feature varience that we would have to account for. For example, to mention only a couple:
We are working to further enhance the features for List View Apps, including plans to provide a more integrated experience on the SharePoint pages themselves.
Are you suggesting that we provide a way for the App Maker to decide whether or not an app will show up in the List Views, even if it was not made from the SharePoint ribbon?
Thank you for your feedback. As soon as I confirm your goal, I'll discuss with the team.
