I use latest versions of SD on iPad3 (v 3.9.5.120) and iPhone 6 (v 3.9.5.120) as back-up. Also use it on IPad Pro (v 3.9.5.120) just for planning. Every time I use SD on the iPad3 and iPhone 6, and often on the iPad Pro) at some point SD tells me I’m not connected and need to log back in. Been doing this for several months now and it can be distracting & frustrating when this happens in flight or during engine warm up. I’ve deleted and reinstalled the app but this didn’t work. Any suggestions?

SD only allows two mobile devices to be logged in simultaneously.  If you wish to use your Ipad mini and your iPhone in flight you should log out of SD on your ipad pro and then check that your other two mobile devices are logged in.

Thanks, George - much appreciated, I will do just that!

I get logged out every single time.
