You must check which components or extensions you’re using as some of them don’t work in Kodular. If you have any monetization component, remove it before importing your project.
you have to delete, webviewer, notification, all dialogs, space, all ad networks, and all other things which are not in kodular or thunkable.
I think you will be faster if you make the project from start on new. At first it is a good lession for you and you know that you dont have troubles in the future with any components or other things.
I did the same when i changed from appinventor to thunkable, after a while i changed from thunkable to appyuilder and a few weeks later from appybuilder to kodular. And i wasted one or two days of my time to import the aia file. I had to delete so much things that i was faster with start from scratch.
I had a few screens with a few 1000 blocks in the app and i needed 2 or 3 hours to copy all things.
