The Instagram team announced that they have completely re-worked the application for windows mobile 10. Now it includes all the stuff that the other users were having for such a long time.
As you know, the windows store do not have any logs for the changes made, the changes and the improvements are usually caught up by the users:
– Videos are getting played way faster than the previous version
– Graphic re-design
– Photos can be now uploaded directly from the gallery
– The “shake to make action” is now working as a problem reporting feature.
