Amazon and their literature are not always accurate. It wouldn't be the first time they advertised a new device and said it would have certain features, but some of those features didn't show up for a very long time, if at all. Having worked in the software industry for 25+ years before retiring, I often witnessed promised features getting axed at the last moment due to various reasons, however the marketing people were seldom on the same page as the developers, so marketing ads often listed features that did not make it into that development cycle. Marketing people also invented features from time to time, and we never understood why they did so nor why corporate HQ would let them get away with that.

We have already seen discrepancies in the various literature released by Amazon concerning the Drop In stuff. One source states phones are compatible with it, another source says only the Echo, Dot gens 1 & 2, and the new Show are compatible. So even within Amazon there seems to be some confusion.
