When I tried to import your aia, kodular complained with warnings, checked your aia and noticed that your second screen was imported one.
Since I didn’t read thoroughly what was on the warning message and on this point project was already removed
- Message was about TaifunTools
- Message was about ButtonDesigner
added those extensins to your aia and the rest you already know, it works
I have no experience with export/import screens, but extensions were not included
