Was your S pen not working previously? That should have been reported in the beta feedback. My S pen has always worked and I use it all the time. But I use a stock launcher and a theme.
I didn't see your post so I'll delete the same thing I just created as a thread.
And yes! I remember when pentastic didn't work after the 1st beta. But within a week, an updated version came out and fix the issues. It worked through beta 2, then when beta 3 was installed, it stopped functioning again. Hope this is the last fix.
