Are you sure that the imported version of meshtastic in your script is also on 2.2.0, and not only the CLI? Maybe you have multiple versions of the package on your system. Since this check was already removed from the source code here: 055da95

What does this show?

import pkg_resources
print(pkg_resources.get_distribution("meshtastic").version)

Sorry, it was my fault, actually meshtastic was updated to 2.2.0 on a different python ver (I have 2 versions on my PC) but the one driving my application. After updating meshtastic on the correct python version now all is fine.
