P: Sharing to Portfolio: "Photo not synced" Error Message

This issue continues to persist a year later. Is it something that is going to be addressed? Currently the only workaround seems to be to uncheck "Store a copy of all originals. [..]" in the application's preferences.

This thread is being merged into an existing authoritative thread for better tracking and response. Please review the official answer (if any) in the second post on the thread for more information. 

The most frequently occurring problem, whenever I want to share photo from the album to a portfolio connected, the error message showing 'Original photos must be synced to the cloud before publishing', even though photo is synchronized and no process pending shown on the sync icon. This is causing lot of inconvenience and the very purpose of building own portfolio easily from Lightroom CC albums is not served through the creative cloud subscription with this frequent error.

I have the same experience.  I contacted Tech support a while back and they said it may be because I store copies of originals locally. ("Store a copy of all originals at a specific location." checked in preferences.) I don't know about that and I don't want to give that up just to have a more seamless Portfolio integration in Lr. The function just doesn't work properly and it's something Adobe needs to address.  The work around is what @roman mezhibovski  says. Do your Lr-Portfolio integration on the web. No errors and less confusing. 

BTW - another observation - when I do a "Resend" from the Sharing -> Adobe Portfolio in LR i get the same error message.

Im not sure we are talking about the same thing.

I want to add a new photo to a collection and LR wont let me do that - its not a sync issue because the photo never gets added to the Collection in LR in the first place.

My understanding is that this is a "feature" of Portfolio. You have to update manually each collection in Portfolio when you change the collection - Edit Portfolio -> Pages -> Reset from Lightroom. This is tedious but it is the only method I have found for keeping my LR collections up-to-date in Portfolio. In my opinion there should be a setting to allow automated syncing of each collection with Portfolio.

If anyone knows of a better solution please let us know.

PS - if you do this from the web version the problem does not happen.

Steps to reproduce:

1. Select an image Share To > Adobe Portfolio

2. Create new Collection

3. Image gets uploaded and is visible in Adobe Portfolio

4. Select a different image and Share To > Adobe Portfolio > Select previously created Collection

Getting this error every time, even though everything is synced:

@Rikk I am getting this issues as well. Trying to publish to Portfolio photos that have been synced 100%.

As was mentioned, this only happens when trying to add to an existing Portfolio Collection. Adding to a new Portfolio Collection works fine.

This issues is also intermittent but it happens more often than not.

Restarting LR\resetting etc did not fix the issue, is there a way to get this resolved - am not able to sync to Portfolio

PS - I think your instruction are for LR Classic - we are talking about CC (also they are for Mac only...)
