The process of building custom applications and tools that interact with Microsoft SharePoint, including SharePoint Online in Microsoft 365.
Thank you for sharing your concerns.
First, I’d like to clarify that this is a user‑to‑user support forum. Moderators participating here do not have access to backend systems, nor can we directly intervene in Microsoft product functionality. Our role is limited to providing technical guidance and sharing best‑practice recommendations based on reported issues, requests, and scenarios.
Based on my research, this behavior appears to be related to how Power Apps Vibe processes SharePoint data source. When connecting directly to a SharePoint list, the platform relies on the SharePoint connector, which can become slower with larger datasets, especially when the list contains many columns or complex field types. Additionally, SharePoint integration in Vibe is currently read-only and primarily optimized for rapid prototyping, rather than large-scale data operations.

For improved performance, you may want to consider moving your data into Dataverse. As the native data platform for Power Apps (including Vibe apps), Dataverse typically provides faster and more efficient data access, since queries run directly within the platform rather than through external connectors.

Please note that this summary is based on my own findings and may not fully address your concerns. Since this forum does not have a dedicated Power Platform tag, you may receive more relevant guidance by posting your question in the Find answers across the Microsoft Power Platform Community. The reason I suggest posting a new topic there is that in the general Q&A Forum, resources and expertise on Power apps are limited. In the Microsoft Power Platform Community Forum, you’ll find the most qualified group of respondents, and other partners who regularly read the forums can share their knowledge or learn from your interaction.
If you have any additional concerns, feel free to comment below. I would be more than happy to assist.
