Hello,
I had the same problem as @meirha. Also on a Wiko Pulp 4G running Android 5.1.1 and rooted for what it is worth. I could not pass the fresh Play Store Enpass welcome screen, the arrow and the skip button were not working.
Uninstalling the Play Store version, installing the former version @Anshu kumar posted here, setting up Enpass, then upgrading through Play Store did the trick!
Thank you @Anshu kumar
