16 track purchase option - 2 devices

[ViBRATiONLANDER]

hello,
i purchased DAW for my iPad and then the 16 track upgrade the following week. works great.

and then i was able to install DAW on my iPhone after syncing, but the 16 track upgrade did not install along with the app onto the iPhone. am i required to repurchase the 16 track upgrade in order for it to appear on a 2nd device?
thanks,
e

btw, your app is fantastic -- i stopped using sonoma altogether (not surprising since 4-track is a POS)
