I have had this problem ever since I got my Xbox one whenever I share friends game clips or screenshots they never appear in the activity feed or in my profile ... Instead, would it be possible for you to post a screenshot of the email you have received here instead. To take a screenshot, bring the email up and then on your keyboard press the Print Screen key (Prt Sc).

Context Explanation

Then open up Paint on your computer and press Ctrl + V keys together and this will paste the screenshot into Paint.
