Hi,
I recently upgraded to IOS 10.0.2 on my Ipad Air, and found that JRemote was 100% broken: it crashed instantly on launch, even after a reboot.
So I took the normal troubleshooting step: delete the app, and reinstall from the app store.
JRemote will not install from the app store. The "installation circle" spins for a fraction of a second, then the cloud/download icon reappears. So it absolutely will not install. I was able to reinstall the app using Itunes, but it again instantly crashes on launch as soon as it shows the splash screen.
UPDATE:
I was able to fix this by updating the computer-stored version of JRemote using Itunes, then deleting JRemote from the Ipad and reinstalling using Itunes. Then JRemote would work. Direct installation on the Ipad was impossible; not sure if something is wrong with the package on the app store...
