A few years have passed since this request and as a business this would save us allot of time and irritation. As a company we share daily hundreds of links to files via Microsoft Teams with each other.
Now the situation is as follow:
1 link is shared
2 team member clicks on the link
3 browser opens the link to the file
4 user clicks on 'open in dropbox' button
Ideal situation would be that admins and users have a File open preference, where links to files can directly open in the native apps:
1 link is shared
2 team member clicks on it and the file is synced and opened in the native app
Microsoft Teams has a great solution to this problem for Office-applications, called File open preference, see screenshot. It would be great if Dropbox could also build this feature in it's Dropbox-apps.
