Saving photos was lost in their big rewrite back in August. For that reason, I didn't update. Since then, I've kept an eye on my wife's Facebook app (she did update), and I haven't seen any sign of it having returned. So, what is "a while"? As it must be less than four months (if we were to assume that my wife hadn't updated her app since the August update - unlikely, but not impossible), it would be helpful to try to speak in more precise terms.
Sharing was one of the most requested but not present features up to the big rewrite, and it didn't appear with the big rewrite. So, I'm not sure what you mean by "a version or two ago", but if the last "new version" of the app was the one releases in August, then you're simply wrong. If, on the other hand, you're talking about updates, and sharing was introduced in one of these minor updates from Facebook since August, while I wouldn't call those "versions", thank you for the information.
If it seems like I'm being snippy, that's because I feel like your reply was dismissive. As I noted, these have been known issues for some time. If they have been addressed within the lt few months, great. But you don't need to make it sound like they've been fixed for a long time (quite "a while", for "a version or two"), when in fact the longest it could have been is a few months.
