Copilot buttons in OneDrive/Teams/SharePoint work on preview thumbnails, not the actual file. Its been like this for a while and Microsoft hasnt really acknowledged it publicly.

Until they fix it, the workaround is exactly what you said: open the file in the dedicated Copilot chat view. I know its not great UX but at least it works there. For batch processing scanned PDFs, I've had decent results running them through the Microsoft 365 OCR pipeline first (upload to OneDrive, let it index for 24hrs, then Copilot can actually read the text layer). Not perfect but better than nothing.
