PSE 15 smart tagging issues/questions

My sweetheart wife once again got me the new version of PSE...15, for Christmas. The catalog conversion from PSE14 went well. The questions I have concern smart tagging. According to Adobe, photos will be smart tagged as they a downloaded into the organizer. Checked my existing photos, many older ones (2010-2008) are tagged (dogs, pets) but none of the newer ones, EXCEPT for a dozen or so that are not jpg's. So then I took pictures of my dogs (many different poses, close ups, face only , full body, etc.), flowers, misc. objects and nature settings with my camera (jpg's) and imported them into organizer. None of those showed up in smart tags either. My settings in organizer under "media analysis" has "run face..." unchecked, "do not show Smart tags" unchecked and "analyze media for smart tags" is checked. I researched and could not find a way to "smart tag" my existing photos, so thought I'd check here with the experts. Not interested in doing it manually. 

1. How to I get organizer to smart tag new jpg's downloaded from camera? 
 
2. Is there a way to "automatically" have photos already existing in the catalog to be smart tagged? 

Thanks in advance for any replies.
Hoping everyone here had a wonderful holiday.
Cheers,
Roger
