Was not sure what you meant, then i updated. 

Oh dear, it is quite jarring. Additionally, the app is primarily right hand focused so the share and exit buttons on the left hand side are out of reach, so i won't be using them.

I actually think those two buttons are even more redundant because share is already on the three dot menu and more accessible.

My immediate actions to save an image or video would be a long press from the feed or the corner save buttons when expanded. Convenient to the point of a being a reflex - probably why you're seeing the messages.
