Yup, that's what I understood as well.... I got a couple of apps in the Play Store and I work with TapIt on both (I got a pre-3.20 version of B4A and thus I don't have support Google Play Services yet).
Recently TapIt told me I would have to use their 2.0.x SDK that supports the new Advertising ID, but they won't release any further B4A wrapper or library. It means that we (as a nice and supportive community) will either have to come up with an updated library ourselves (like most of the time) or we'll have to move on and skip TapIt because B4A is great and I for one will certainly upgrade.
