The Instagram beta for Windows 10 Mobile has been updated, bringing some translucency to the Live Tile, the ability to login to a Facebook account and a few other changes.
Improvements appear to have been made in using the camera, as you can now tap to focus different areas of the image.
These improvements make the app even better to use, even with it still being in early beta. You can grab the latest update from the Windows Store now!
Thanks for the tip, Ahmed!
