Thumbnails not working/showing for NEW .cr3 files

[Bonefish75]

Added 100 new .CR3 files (Canon RAW files) to Onedrive and thumbnails won't show. This just became an issue in last 3 days. Thought it might be camera setting...but..I copied older cr3 files on onedrive to old and new folders, same outcome :-(. Maybe a forced update or any other ideas from the group? Thanks in advance ☺️ - Bonefish75

Best to check Canon forums. Custom image/file format viewers (that generate thumbnails) are largely at the mercy of the format owners. When Microsoft includes all of this stuff out of the box people call it "bloat" 🙂

I have the same problem. The issue is caused by OneDrive. If you copy the images to a folder outside OneDrive the thumbnails will show up.
