When I share an album, panoramas are missing

If you login to your Adobe account using the LrWeb interface in a browser window (login to lightroom.adobe.com), you'll see all your albums listed there. You should see an "Albums" tab and alongside it a "Shared" tab. Click on the "Shared" tab and select the specfic album from the list. In grid view are the panos showing? If they are not showing there, can you post two screen shots of the grid, one taken in Lightroom desktop, the other taken in the LrWeb interface, that'll help show the Adobe engineers that there is an issue. 

But if they ARE showing in the LrWeb grid, switch to the Display tab (click on the icon that looks like an artist's palette at the bottom left of the grid in LrWeb), that then shows the view that the viewers of the shared album should get when they open the link. Are the panos still showing there?

Apparently I'm not really the one to offer assistance to you. I have the panoramas in an album that I'm sharing from Lightroom Classic, but the panoramas were actually created in Classic. I do very little of my main editing in Lightroom. I experiment with it, but prefer Lightroom Classic. I have no idea why the panoramas are not displaying as you expect them to. Sorry.

JimHess - The Help|About Lightroom dialog says 'Adobe Photoshop Lightroom' Version 4.4. BTW, I went to college at Wesleyan with a Jim Hess from Philly - one of the smartest guys I've ever known.

Lightroom CC is old terminology. There is Lightroom Classic and Lightroom. What is the exact version number of Lightroom that you are using? Incidentally, all of the panoramas in my collection were created using Lightroom Classic.

My panoramas were made in Lightroom CC on my laptop. They were made from jpq files and the panoramas are dngs. Definitely in my album. I share them on Facebook by exporting and uploading, and this works fine, but I was trying to show a poster all my photos heading up Mount Whitney and when I checked, no panoramas were included, nor were the merged files. 

I just check one that I recently made, it seemed to be outside the Album. I moved it in and now it's in the link.

I just sent myself a link to one of my collections that contains only panoramas, 15 of them, and I was able to click on the link and everything worked as expected. LrC 10.4 on Windows 10.
