Where's the widget to add a Dropbox folder to the main screen of my Android device?

Thanks for posting on our Community, samassi76! Welcome aboard. 

Are you referring to the steps that are described in this Help Center article perhaps? If yes, you can create a Dropbox folder shortcut on your Android device that way. 

Let me know, if you need something else.

good morning Nancy, you know the procedure well, on my previous Android I had done it. I just got the Xiaomi 15 Ultra and there is no this very useful possibility.

Hey again, samassi76! Can you send me a screenshot of what you see when searching for Dropbox in your widgets? 

If you tap on the Dropbox app for a bit longer instead and then select your Dropbox folder, are you able to create a shortcut then? 

Finally, what’s your current OS version?
