For some FamilySearch images that I previously viewed, I started getting a popup error message: "This image is unavailable for online viewing at this time."
For example, https://familysearch.org/ark:/61903/3:1:33S7-9RJS-3WL?cc=1911121&wc=Q6WY-SZX%3A183208301%2C183361201%2C192384601. I knew that I had previously viewed the image as I had the FS citation: ""North Carolina Estate Files, 1663-1979," database with images, FamilySearch (https://familysearch.org/ark:/61903/3:1:33S7-9RJS-3WL?cc=1911121&wc=Q6WY-SZX%3A183208301%2C183361201%2C192384601 : 21 May 2014), Caswell County > N > image 6 of 18; State Archives, Raleigh." A review of the catalog page shows mostly Film icons but still a few Camera icons: https://www.familysearch.org/search/catalog/456833?availability=Family%20History%20Library
I reported this to FS and received this reply: "We believe this to be the result of a known bug in the catalog. The cataloging department has asked us to have users contact them directly about these access issues. Please send an email to FHL-SLC-FilmRequests@churchofjesuschrist.org and report the problem. Please include the link to the catalog entry where you see that some still show camera icons. We hope that the catalog department will be able to restore online access for you." If you experience the same issue, please report it.
