Agreed. The feature set is in desperate need of the search option both on approved photos and when attempting to approve additional photos. Very often I have to go into the photos app, find the photo, make a mental record of approximately where it is in history and scroll scroll scroll. Obnoxious and cumbersome.
What I really want is to create a special photo album for (Facebook/Instagram/Slack/etc.) and have it automatically gain access to whatever photos I put in there.
I think they have because with chatgpt you click the photo icon and it uses the system photo picker to pick a photo. I guess Meta deliberately isn't implementing that
