He donado y sigo sin poder usar APP Inventor 2

He donando 5 $ pero sigo sin poder usar APP Inventor 2. Sale pantalla en blanco

Try this for ai2 server:

https://ai2.appinventor.mit.edu/?autoload=false

or, if you use the code server:

https://code.appinventor.mit.edu/?autoload=false

Access to AppInventor is not related to the giving of a donation.

OK. Tanks

The problem with a blank screen appearing should be fixed.

To be clear, no one is obligated to donate. And once you (now) see the solicitation screen and click past it, you should not be bothered with it again.
