MIT App Inventor Help
#1

Buenas tardes,
Inicialmente me gustaría felicitarlos por su página MIT app inventor 2 ya que gracias a ella he podido aprender a programar aplicaciones para uso personal. Una de ellas la desarrolle desde hace 2 años. Y la aplicación la utilice en dispositivos desde el Android 8 hasta el Android 12 sin ningún tipo de problema.
Esta misma aplicación la actualice sutilmente, ya que tenía unos pequeños errores.
Pero al intentar actualizar la app no me lo permite, argumentando que el paquete no es válido

sorry to bother but I received the same error when I use App inventor Serial component. The error appears with android 12 and 13 but not with android 11.
I have written in another chat too, the problem was identified and, reading the chat, it was solved but working in app inventor official site, I have the same problem, do you have any idea to solve it?
Thanks
Mirko

for now, use the test server which has the fix (you also need to use the test server companion app)
