The process of building custom applications and tools that interact with Microsoft SharePoint, including SharePoint Online in Microsoft 365.
Hi @Ethan Evers,
Thank you for sharing the detailed explanation.
Based on your description, this issue appears to be related more to the Power Apps Vibe preview experience than to a standard SharePoint Development issue. Power Apps vibe (preview) shows that SharePoint lists can be added as a data source in Vibe, but the feature is still in preview and is subject to change.
In particular, SharePoint lists are currently read-only in Power Apps vibe, and some column types such as Location, ManagedMetadata, Calculated, ExternalData, and TaskOutcome are not fully supported and are converted to text columns. That could help explain why the table appears to connect but then becomes unusable or does not behave as expected in the app.
Since your issue is happening specifically inside the Vibe app-building experience right after adding a SharePoint list through the Data tab, it is tied directly to Power Apps data-binding behavior rather than standard Office features.
Because of that, I highly recommend reposting this in the Power Platform Community, specifically under the Power Apps forum. That space is actively followed by Microsoft MVPs, platform developers, and experts who work directly with Vibe and SharePoint connections every day. They will be much better equipped to pinpoint exactly why the data is misbehaving and give you a quick, practical workaround.
If you repost there, it may help to include whether the list contains unsupported column types, whether the same behavior happens with a simple test list, and any error message or session details shown during the connection attempt.
- The official article for adding a SharePoint list in Vibe is here: Add a SharePoint list in Power Apps vibe (preview).
I hope this helps point you to the right support channel.
