When you look at the single app subscription plan PS is listed. It is listed as PS, not PS CC which I figure is just a typo. I'm wondering why Adobe would even offer it in that grouping. If PS is all you need would't make sense to get the photography plan with 1TB storage for $20 a month instead.
Besides how do you get or sync files to the cloud? I see share with Behance. LR CC sends files up but LR Classic CC only sends smart previews when you sync.
