Big Update
As stated above, we are working on a huge update to address most of the issues and make sure that Kodular keeps running for more years.
At a glance, this update will bring Target SDK 32, and will (finally) integrate the new Android file system, so all related bugs to that problem should be solved. It will also include new features and minor improvements as well.
But it will also finally deprecate Google Admob components, as they will no longer be available, even for existing apps. Thus, migration to Google Ad Manager shall be mandatory by that date if you want your app to target Android 12.
We are aiming to launch this update on the 26th of June 2022. We will keep the community up-to-date if this changes at any point.
