Currently, mixed use (Personal and Commercial accounts on the same device) is not supported.
If you have used an account with a license on your computer, then TeamViewer will recognize that the computer is used commercially. When you sign into your Computers & Contacts with your <Company Email> the license is associated with the computer. Once you sign out, and sign in with the <Private Email>, you are getting the commercial use suspected message because the computer had a license attached to it. Once the computer is used with a commercial license attached, the TeamViewer ID is classified as commercial.
