Oh I see there is a completely different interface when uploading photos directly vs importing from Flickr. Since I import all photos from my Flickr to maintain the metadata link it must be using an older less flashy form.
Didn't even know the one in the video existed until now.
Yes, I usually upload my images directly into iNaturalist, so it usually suggests an ID for me when I put an ID on each observation.
I found an iNat page on uploading observations from Flickr [1] which is probably what you used. It seems to say you can add an ID for each upload but it doesn't say if the AI will help you with the ID, like with the direct uploading to iNat.
See these iNat Video Tutorials for examples [1]
