Warning triangle when download fresh Photos library from icloud.
I have a very frustrating issue with apple photos library that I can't troubleshoot despite rebuilding the photos library and downloading from fresh icloud. If I take a photo from my iphone and share it to icloud to synch with my 2 other computers (1 macbook pro, 1 imac), every photo taken on my iphone shows up with the grey warning triangle whenever i double click the small image in the library to enlarge it on the imac... no issues on the macbook pro. anything taken via SLR and then uploaded is visible everywhere.
I assume this is a permissions issue somewhere between icloud and the imac - but it's very very frustrating.
as above, i've repaired, rebuilt and resynched with icloud to no avail.
any advice would be great !
