I've found a few reports of this around the Internet of similar issues, but no resolution so far. I know it's not really that en vogue to complain about problems on Facebook that aren't broad, democracy-damaging issues. Still, I do use it to keep in loose touch with a lot friends and acquaintances, so I'd like to be able to post photos in albums! I basically haven't been able to this from my phone since May 2019. I tend to post travel photos in albums (that's my inner need for organization) so I know that the last time it worked for me was May 16, 2019 (if we're not Facebook friends, the link to that specific post obviously won't work).
Whether I'm posting from the album (as shown in the above first screenshot), from the main News Feed input field on the app (screenshot 2), this same thing happens to me. I've tried all sorts of changes to both the album's privacy and the general posting privacy settings I have on Facebook. This screenshot from today of the Taiwan & Myanmar album in particular shows how absurd this is: the album is *public* and I still get the warning, "Please Change Your Audience: You can't exclude this smart list from your audience. Please select each person who you want to exclude or choose a different audience."
Needless to say, I am not excluding any smart lists. In the last few months that I've been having this problem, I've reported it multiple times, taken screenshots to include with the reports, and while I don't really expect to hear anything back, it is software testing in a production environment that I feel like I'm doing for free...
Facebook, please fix your shit! If only so I can post stuff again and generate more page views and ad revenue for you.
While you're at it, could you make it possible to create posts in albums from the desktop website? I don't understand why there isn't feature parity between the mobile app and website.
