When viewing an image in the main feed, the save and share icons are still missing if you're using compact mode. Disabling compact mode brings back the icons, and the icons are visible if you open the image from within the post.
This is from clicking the image preview directly in compact mode right? I seem to have the save and share options in compact mode, but not sure why different from you.
Edit, sorry, ignore. I had not updated to the latest version yet. I also have the same bug now.
