URGENT Loss of critical album

I created an album "Cyclades".  It appeared and functioned perfectly on both my iPhones.  I went through 88,000 images and added 500+ photos of the Cyclades to the new album.  (I already have 147 albums and never have had a problem.). Suddenly the album disappeared from my library.  I looked for it both through the program and on the cloud.  Fortunately I shared the album with myself and another person.  The link still works perfectly and goes right to the Lightroom.Adobe.com site and displays the photos.  But they are viewable only and not downloadable nor transferable back into the program. Adobe tech support and I have been in tooch multiple times. They checked whether they might have been in some other Adobe account..  They had me set up the album again with the old name saying it would repopulate the photos. It didn't.  So we know the photos are there in the Adobe cloud and I can access them and view them. But some malfunction has removed the link to their home.  It would be extremely costly to go back through the 88,000 photos. So I seek a solution based on the fact the album is still alive and intact.   Can Adobe instruct the file to allow jpg downloads so I can download and reinstall them all? When I open the file on the Cloud  it asks if I want to add new photos!  Thank you.  Robert
