Facing Share IT problems after upgrading from android kitkat to Lollipop

After upgrading my tablet to Android Lollipop 5.0.2, I have tried out the ShareIt app and it completely refuses to work. I understand the app is supposed to work by creating a wireless connection that members connect to and make it possible to share files. Are there any settings that must be changed in Lollipop since it was working well on KitKat? I believe it is not a problem with my connection, if it is please advise me. If you have solved a similar problem, guide me through the process.
