Here is a workaround that was "good enough" for me. The trick is to choose your pic FIRST:
1-Go to your Gallery or pic FIRST
2-Can use the pen that came with Samsung to crop, write on pic, highlight, etc and all the functions you have with Gallery.
3-Look for the "share" icon. (Looks like a left pointing 3 dots arrow)
4-Select to share with Message+ app
5-Choose recipients like normal or simply choose the Message+ icon
6-It will take you to the Message+ area like it used to. You can view your image, recipients, type texts etc. Everything similar to not so distant past. Just like in the good old days.
