Knowledge module causes errors and a lot of mindless blinking

I'm trying to add knowledge bases to my agent, but a lot of Sharepoint entries are causing errors. Now the entire view is constantly blinking, and I don't see an option to remove the ones that are apparently causing all this drama.

Am I the only one with this problem? Anyone has an idea to how I can remove these, so the blinking stops?

Hi,

this is a known UI issue that can happen when multiple SharePoint knowledge sources fail to load simultaneously, causing the page to get stuck in a refresh loop.

Here's how to work around it:

Option 1 — Remove via URL (bypass the broken UI)

If the Copilot Studio UI is too unstable to click through:

Open your browser DevTools → Console

Try navigating directly to the Knowledge settings URL: --- https://copilotstudio.microsoft.com → your agent → Settings → Knowledge

Use a different browser or InPrivate/Incognito mode — sometimes the blinking is cache/session related and clears up

Option 2 — Clear and re-add via a stable session

Hard refresh the page: Ctrl + Shift + R

If the page stabilizes even briefly, quickly click the "..." menu next to the failing SharePoint entries and select Remove

Remove the broken entries one at a time, then re-add only the ones you actually need

Option 3 — Check SharePoint site permissions

The errors are likely caused by SharePoint sites your agent can't access. Verify:

The sites are publicly accessible within your tenant or the agent's service account has access

The SharePoint connector is properly authenticated under Settings → Security

→ Add knowledge from SharePoint

If none of the above work, raise a support ticket with Microsoft.
