[TIPS] PowerApps Form doesn't show up in SharePoint List or not the expected size (squeezed)

Issue:

   When trying to use PowerApps form in SharePoint list, the PowerApps form doesn't show up.

   Even PowerApps form showes up, its size is not the expected Lanscape orientation, but a squeezed window.

Solution:

    I think this is a bug of PowerApps/SharePoint.

    The workaround is create a new list from the existing list and try to use PowerApps form.

     If the PowerApps form shows well in the new list, then create a Power Automate flow to copy the data from your issued list to the new list.

I tried creating new list from existing list twice.

In the first try, the PowerApps form showed up, but squeezed size.

In the second try, the PowerApps form finally showed well.
