Faced the same issues, was using Chrome. I tried in Microsoft Edge and it worked for me.
Why are files not being added to Copilot Chatbot Knowledge base?

I am having issues uploading files to a copilot studio chatbot that I have been building for my company. Every time I click add after uploading a file, it refreshes the page and goes back to the main knowledge base page but does not add the file I uploaded. Has anyone run into the same issue and been able to solve it? This has happened before and was solved within few hours or next day. But this time, I have been trying to add new files from last week but every time after adding new files it immediately only shows me the list of old files only.

Russell H. DeGrove 6 Reputation points2024-09-16T18:06:02.95+00:00 Is doing this in both Chrome and Edge. Impacts one specific bot, naturally the one that I have put all my efforts into for the past couple of weeks.

Michael Malay 0 Reputation points2024-12-18T20:13:38.73+00:00 Same issue here, when adding files one by one, it will add to the list of knowledge sources then it will error out, when adding multiple files it will show an error on the "Add knowledge" menu. If I refresh the page then the group add will show in knowledge source but will also show the error icon. All documents are PDFs, not exceeding 512MB is size, have tried in Chrome and Edge, cleared cookies and site data in both, still get the same result. The article below says that PDF is supported sooooo.... not sure what's going on with this.
