If you have a project with the settings plugin applied, and the assistant has to upgrade your project, it will not change the version of the settings plugin.

I had a project with using 7.4.0-alpha02 in build file and in settings.gradle, and it triggered a forced upgrade when opening with Flamingo Canary 2.

The assistant changed the version of the app and library plugin in build.gradle but left settings.gradle untouched.

The content of that file had this section:

plugins {
    id 'com.android.settings' version '7.4.0-alpha02'
}
