photos gray in iMac People after reposition or merge
On my updated iMac with Monterey 12.2.1 and 32GB RAM, in "People", each time I try to merge two people or to reposition a person (because, unaccountably, Photos doesn't provide alphabetical sort), half or all of the thumbnails are totally gray. The merge may or may not happen in my lifetime, even if if I close and reopen Photos. The move often seems more likely to happen if I close and reopen Photos. Meanwhile, albums shared with me continue to display empty gray boxes with a little cloud in the corner. I have opened Photos with opt-click and allowed "repair" of the library with no success. All other programs are working fine.
