Hi Rikk. One remaining issue.  Prior to the appearance of the bug in September 2020, LR would save originals in the NAS (when connected) per my settings in Preferences.  When not connected to NAS, LR would automatically save originals in the default Adobe LR AppData file.  When reconnected to NAS, LR would automatically move the originals (stored on laptop's HD in that default Adobe file) to the appropriate file on the NAS.

With the LR 5.0 update installed (following install of Windows 11)—if NAS is not connected, LR shows the files on the Import Preview screen.  However, import of selected files causes a window to open stating "These files could not be downloaded" followed by the filenames.

So, to import photos when not connected to NAS:

1. I must go into Preferences and under "Store a copy of originals at specified location,” I must select the Reset button—which points LR to the default Adobe LR AppData folder.  After selecting Done, I’m prompted to restart LR
2. When restarted, LR now thinks it should move all the originals to the local HD, so it starts “checking” 60K+ photos (even though the local HD does not have nearly enough capacity—which is why I store the originals on a NAS).  Even if I deselect “Store a copy of all originals at the specified location” (again, the default Adobe LR AppData folder on the local HD) and restart LR, LR wants to index (“check” and “move”) all 60K+ photos.
3. Appearing in the “Checking Photos” window is a “stop until next launch” button, which stops the indexing.  Now, I can use LR while not connected to the NAS.
4. Having taken these steps, I can now import files to LR.  Smart Previews are stored on the local HD and are fully functional.  Originals, if needed, can be accessed in the Adobe Cloud when connected to the Internet.
5. And new images can be imported into LR with the original RAW files stored in the default Adobe LR AppData folder.
6. If LR is restarted for any reason, LR once again begins indexing the 60K+ photos so I must select “stop until next launch”

When the local HD (my laptop) is reconnected to the NAS:

1. I launch LR.  I stop the indexing of the 60K+ photos.
2. Going into Preferences>Local Storage>”Store a copy of originals at the specified location”, I browse for and select the NAS
3. When LR restarts, LR indexes only those files that were imported since LR was last connected to the NAS. LR moves the originals from the default Adobe LR AppData files on the local HD (freeing up space on my laptop’s HD) to the NAS.

To summarize: prior to the introduction of the bug in September 2020, LR stored originals on the NAS because those were my Local Storage settings; when not connected to the NAS, LR would automatically store imported files (Smart Previews and originals) in the appropriate default Adobe LR AppData folders; when reconnected to the NAS, LR would automatically move recently imported originals to the appropriate folders (per my previously selected Local Storage Preferences) on the NAS.

I’m relieved that I can once again use LR when my laptop is not connected to the NAS.  I’d be satisfied if LR once again could automatically determine where to store originals contingent on whether my laptop is connected to a NAS.

The team is still working on your issue. 

Done. How would you like me to send it?

Engineering request: The team would like to collect a diagnostic log immediately after experiencing the error.  Can you provide one?

4.2 had no fixes related to this. It is still in progress. 

Hi Rikk.  Just updated to LR 4.2. Windows, drivers, anti-virus, Synology DSM all up-to-date.  Turned off NAS, restarted LR. Problem persists. Event Viewer gives the same error message.  In summary, this six-month-old issue still persists after v4.2 "bug fixes"

Thanks Rikk.  I can not tell you how much I appreciate that you looked into this and have reported it as a bug.  When the issue is repaired, I would welcome the opportunity to discuss with a supervisor the absurd responses I received from Adobe LR tech support staff--none of whom would even entertain the possibility of a bug
