In the future, will it be possible to set direct comments on PDF viewing in the iPhone client and synchronize the changes directly to the cloud?

Hi there @sdfgsdfg, thanks for reaching out to us on the Dropbox Community. 

Comments you add to your files from your mobile app should show up on the website as well. 

If this isn't happening, could you clarify if the comments appear only when previewing a file on the mobile app or the website? Does this happen to only .pdf files? 

Let me know how it goes - thanks!

1 Can't seem to comment on PDF files on my phone
2 I am talking about simple annotations in the cell phone client, including adding underline highlighting and other operations, because it should be able to achieve incremental synchronization, which will be very convenient when reading PDF. Adding a dropbox account should not achieve incremental synchronization.

Is the .pdf you're trying to comment a shared file, part of a shared folder, or was sent to you via a shared link?

[sdfgsdfg]

It's a file in my own network drive, not shared

Could you check if there is an option from the ellipsis (...) button to enable comments when you access the file from the website?

Keep me posted, @sdfgsdfg!
