Inspy App closing unexpectedly
Inspy app was working fine till yesterday. I open the app and it imediately closes. I tried uninstall/reinstall,shutting down phone and restarting,restore phone from my most recent backup. App still closes imdediately after I open it? I also have a paid subscription for app and there's no way to contact the app developer. I'm aware of the recent bugs with this app but it has been working fine up till now. Asked friends with exact phone (6 plus) and app,they have no problems with it. I love this app and any help in solving this would be appreciated.
iPhone 6 Plus, iOS 11.2.6
