Has anyone else noticed the DJI Go App seems to disconnect more since new IOS 11.4 was released. i updated to latest version of IOs 2 weeks ago and when flying this weekend I got 3-4 DJI go app disconnects. What i mean is on the DJI Go app screen in the upper left is goes from connected/GPS to disconnected and in 2 of the cases the screen went blank for a few seconds, other cases screen did not go blank but froze only latest for about 5 sec or so but kind of un-nerving. I was able to get the spark to hover in place till application reconnected so nothing bad happened but really strange. I have been flying same two areas for past year so it would not seem to be an interference issue. Also spark is calibrated and remote full charge and iPhone full charge so as an IT person my thought is something in the new IOS is not yet been updated in the DJI go mobile app.
