Reverting to default SharePoint new item form instead of PowerApps custom form

Maybe you’ve made a PowerApps customized form but want to switch back to the original SharePoint new item form. Here’s how:

1. Go to list settings
   • In Modern view lists, click the settings wheel and “List settings.”
     
   • In classic view lists, click “List” from the ribbon menu and “List settings.”
     
2. Click “Form settings” under General Settings
   
3. Select “Use the default SharePoint form”
   
4. OK

If you wish to delete or remove the PowerApps form from the list completely, after you’ve selected “Use the default SharePoint form” you can click “Delete custom form” under the PowerApps option.
