This app is so necessary but it acts up so much! It will literally not back up over 500 media items but I am always connected on WiFi. So the only time media backs up fully, is when it is open. It has been wanting to update for weeks now but everytime I click on "Update" it doesn't do so. What is going on? I am so unhappy. This is unacceptable actually. If anything happens to my phone, I am solely relying on it to store information safely. So if it is malfunctioning, what is the point???
