I’ve noticed this happening recently in one of my bases as well.

Assuming that the file type is one that will show a thumbnail (png, jpg, etc.), I’ve been having to delete and reupload the attachment to get it to show.

I must ask - is there a chance that these failing attachments were added with URLs from Airtable’s CDN itself?

Ultimately, I suspect it has something to do with this.

On my end, these were files uploaded directly from my computer. I’ve found that the issue is often with the thumbnail alone. The file itself displays correctly when opened or downloaded.
