A spokesperson has explained Instagram's proposed timeline changes: "As Instagram has grown, it's become harder to keep up with all the photos and videos people share. This means some people don't see the posts they might care about the most. "We're focused on optimising the order and making it more personalised -- all the posts will still be there, just in a different order. Ad frequency and order will stay the same." However, Instagram has yet to clarify whether the changes will be optional or statutory.
