Apk not traininig, but AI companion works fine

[neragr]

Hi,
I have an app inventor project with ml4k plugin and it works fine using AI companion connection.
But when I generate the apk, I get an error that said the model has not been trained. I've used "Train new model" block and I've programmed a delay after that to wait until the model has been trained
Could you help me?
Thank you
