Hi ​@Mattwing, I‘ve just tried (on iOS) and I can see the Instagram sharing option. Do you have the Instagram app installed on your phone too (and are logged into it)? It seems that Strava is offering the recently used apps on the sharing screen. 

Hi Jana, I do have it and have opened it as well and its not showing up?

Hmm, I’m not sure why it won't show up in your list of apps... 🤔 what if you tap “More” in the top right corner? And, id you still can't find it, perhaps attach some screenshots here so that someone may look and advise 🙂

​@Jana_S Yeah its odd because everything else shows up (facebook, linkedin, snapchat, threads). Not sure if there something in Instagram itself I need to set up?
