Does anyone know how to fix the free license after switching phones?

I use TeamViewer to support my family and in-laws under the free license. Many times I connect using my smartphone. This works fairly well most of the time.

However, after switching to a new phone and installing TeamViewer my new phone cannot connect because it says the license is not compatible. Teamviewer worked just fine on my old phone, but not at all on my new one.

I'm using **third party content** until I resolve this issue.
