Upgrade disabled the program in iOS11. – iSafeBox - Data Guard Review

I have use this program for several years, and have never had a problem until recently. Now, every time I try to log into the program, it flashes a message indicating I need to activate iCloud in my settings. I have assured that iCloud is turned on, I have turned it off and turned it back on trying to alleviate the problem. I have shut the phone down and restarted assuring iCloud is on; however, you cannot get around this error message. As such, all of my passwords are now totally in accessible. I have emailed the developer on their website, but have received no response of any kind.
