Thank you for visiting the Community and sharing your question with us.
May I kindly ask you to check if your TeamViewer license comes with Mobile Device Support (MDS) please? You may be able to find it on the TeamViewer invoice. For mobile connections to mobile devices, it does require the additional MDS with the licences. If you are interested in getting MDS, feel free to contact TeamViewer Sales Team ☎ for checking the current offers.
Meanwhile, you are able to use the TeamViewer license as usual for remote connections from mobile devices to desktop devices.
Hope my explanation helps to understand the setup difference a bit more clearly.
