Some times I get a (recording disconnected unexpectedly) or it just disconnects or on longer flights when I turn the record screen off it does not give me any option to save it. Seems to work on flights that are shorter like 2 minutes or so. Is there a time limit or file size limit and if so how do you change it. I am using an Ipad air 2 16 GB and the latest firmware and Litchi app.
