Adjust for old iOS 12~13 devices

[GusuNinja]

Hi

I have a small problem with my game and using the RequestAppTrackingAuthorization functionality in my game. When using the function on ios 12 and 13 the function just stops and does not ever do a callback. When looking in the document it said it might return a -1 Action but this doesn't seem to be the case.

Do I just add a check if it's iOS 14 or is this something that Adjust will add in a future version? Just want to know the correct way implement the functionality. Currently using 5.4.4.

Thanks beforehand
