Question
Content Credentials warning after reopening TIFF files
Photoshop 27.11.0 on macOS 26.0.1.
With Content Credentials enabled, TIFF files record edits correctly and show no warning after saving. After closing and reopening the TIFF, Photoshop reports that some edits or activities may not have been recorded.
The same workflow with PSD files works correctly.
The issue is reproducible with newly created TIFFs and without scripts or plugins. TIFF files also create a .c2paws sidecar file.
Please investigate the Content Credentials handling of TIFF files.
