Quando accedo su app inventor 2 mi reindirizza nella pagina iniziale e mi segnala: “errore interno o timeout della sessione”
Per favore potete risolvermi il problema?
Has it ever worked for you before?
you might want to go to the Settings and choose "Disable Project Autoload" and restart App Inventor
Are you able to create a new project now?
Probably your existing project is corrupted somehow?
You might want to import your latest backup and restart from there
