Unsupported file formate (RAW / TIFF) when uploading from Lightroom

bmetaylorbmetaylor Detroit, MIRegistered Users Posts: 12 Big grins

I have uploaded a large number of photos to SM using the SM publishing service in Lightroom Classic without issue. All of a sudden, it is now saying that my same RAW files (CR2) that uploaded perfectly fine previous to this are no longer a supported format. The LR app and Camera Raw are both up to date on my computer. Any help would be greatly appreciated.

Thank you in advance,

    Hi BT,

    Please check your publishing manager settings and under File Settings please make sure the Image Format is JPEG as shown in this screengrab:

    Then, can you give the publish another try?
