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?
