I have had a few issues. Finding out the timelapse oscillation issue is due to the osmo hardware and can only be fixed in post. Then the motions I would set would not run completely to the end. But the worst one is if I am not in a place with cell phone reception the app tells me I am not authorised to use it. Which makes the app useless. This is some kind of security to protect against people using the app illegally? It makes it harder for people who have actually purchased the app. This should be fixed asap or perhaps refund the money. It's got good potential just like the Litchi for drones, but fails right now. Hopefully an update will come soon and fix these issues. UPDATE I have dropped another star. My app would not work at all anymore. Kept asking for me to buy it when i allready bought it. I uninsulated it and reinstalled it so I could get it to work again. Agree with other reviews. It's not ready for sale this app. Needs a great deal more work.
