An issue when i try to download the the apk file after i build my project

I made an app full of audio files , its size will be around 30-40 MB , i Build it to a .apk file , it builds successfully without issues, but when i try to download the built apk file , i can't download i get a page saying https://ai2.appinventor.mit.edu/b/2wrsf is temporary unavailable , but i can download my other small project after i build then
What the issue ??

That's a big project, too big to pass through the AI2 server orifices.

Export the aia and try to build on code.appinventor.mit.edu
