What should I do if a file will not open?

1. Confirm that the file type appears in the supported-formats list.
2. Check the internet connection on the presenter device and shared screen.
3. Start a new session and try the file again.
4. If possible, export or save a copy as PDF and try that version.
5. If the issue continues, email hi@wtf.now with the screen platform, presenter device, original file type and a description of what happened.

Do not send confidential presentation content unless support specifically requests a safe diagnostic sample.
