Why do some PDF's open to preview and some require opening in browser?

Why do some PDF's open to preview and some require opening in browser? This is annoying when sharing a your board over Zoom or similar platforms. Is this the way the PDF is saved before uploading OR file name even though no special characters are included in the name? Its not all PDF's on our board and opening multiple times can sometimes clear the problem?

Hi Steve,

I haven't been able to reproduce this quite yet but we're glad to help troubleshoot with you. Are you using the Trello desktop app, or were you viewing that PDF through Trello in your browser? I'm thinking this might be something that's best handled through our support team. Could I trouble you to write us through our contact form here, and we can take a closer look?
