As soon as Kodular releases their SDK31 upgrade, the new android:exported requirements most probably will be fixed, but only for the Kodular components.
There are also some extensions, which need an update and this is not the responsibility of Kodular, but the extension developers.
You already now can start to find out, if it is only a component or an extension which needs to be updated…
Alternatively just wait until Kodular releases the update… if your project then works, you are lucky… if not, then it is an extension which also needs an update…
