[ As I responded to you in another 'Group' in this Forum ... ]
You are not alone ...
There seems to be some sort of problem/issue with the loading of "Memories" ...
You are not the first to raise this sort of problem/issue of late ...
I posted some images in memories yesterday. They are not showing up so I uploaded some of them again and they showed up with "duplicate" over them. When I opened up the memories again, they are not showing again. Any suggestions?
Can I suggest that you check out these "Knowledge Articles" in 'FamilySearch':
Why isn't my photo or document uploaded yet?
Why does it say that my photo is restricted?
What rules apply to uploading memories to FamilySearch.org?
I do not know if these will help.
Perhaps, there has been a NEW "Change" (ge. upgrade/release) to 'Family Tree" of 'FamilySearch' that is causing such problems/issue; or, even, that there is a "Backlog" of "Images" that need "Vetting" before they can "Appear".
As an aside ...
Can I humbly suggest that, if, you have not already done so; then, you consider making this suggestion of yours in the (Temporary) replacement to the OLD 'FamilySearch' ("GetSatisfaction") 'Feedback' Forum, being the (NEW) "IDEAS" Forum, which is currently part of this "Community.FamilySearch" Forum.
This 'Group' being "Family History Research", in this "Community.FamilySearch" Forum, is more about helping Users/Patrons collaborate, learn tips, and share resources with one another; as, the "Description" for that 'Group' implies, rather than as a 'Feedback' medium to 'FamilySearch'.
The (NEW) "IDEAS" Forum is MONITORED by "Official 'FamilySearch' Representatives" (eg. Product Managers; and, Engineers/Developers) responsible for the "Design" and "Development" of 'FamilySearch'.
Just a though.
I have also seen this and reported it to developers.
in my case it would fail to upload to an album
but then I would see that it had been loaded to the general gallery - just not loaded to the specific album I intended.
