Uploading photos to Facebook marketplace won’t work

Hello

I took some photos on my iPhone of things I want to put on Facebook Marketplace. The photos have synced to the Mac Photos app, and I created a For Sale album, moving the relevant photos into this album.

I’m using safari, I go to Facebook, add a new listing, click on add photos, choose files to upload window comes up, I click photos under media on left hand side, click photos in the centre of the window, all albums come up, I find my for sale album and there’s nothing in there to select. If I click on other albums there are photos there.

Can anyone please help? It’s really frustrating.

I’m using macOS Monterey
