Hello,
I have a trouble to get mp4 URL’s working, when they are generated by Formula for Attachment field.

Situation:
Attachment {Attachment} field has some mp4 files in it.
Formula field refers into Attachemnt field.
{Attachment}

Result is an URL for mp4 file. Clicking the URL opens a new window with video file, but video file won’t get started. However, Video file works, when clicked directly in Attachment field, but not via Formula. I need to open it via formula.

Is there a work around or way to fix it ?

Windows 10, Browser chrome.

thank you,
Lassi
