Hi ​@Dazza73, you can share the photo/map from the mobile app if the activity is not set as private. Then you'll see the sharing button next to the comments button. 

However, if you're referring to the neat small overlay text, that's gone, replaced by a redesigned feature… there's been a lot of discussion about that, users are asking for the original functionality, if you want you can join the conversation here: 

Hi. Thank you for your response.

The redesigned feature is what I’m chasing. I see people share this on their various social media platforms.

My activities are not private. I go to share options, and don’t have the option to share the redesigned feature.

I have posted a pic of an example of what I am referring to. 

Thanks,

Oh - thanks for the image, that explains what you mean  So when you're on the sharing screen, swipe through the map/photo options till you get to this “transparent” one. You can then use it as an overlay for any photo.
