Appinventor often is busy.are there offline appinventor?

:pensive: :pensive: :pensive: :pensive: :pensive:

If the appinventor does the save by clicking the button, the speed will go higher. Automatic saving lowers speed.

See here:

Looks like there might be a space after the word Crossword and before the .aia in the filename of the project you’re trying to import.

Also, you may want to try accessing online version via the following URL and see if it behaves any differently:

The servers are never really “busy”. They’re dynamically spun up/down based on average usage with the goal of keeping response times for a given request below 500 ms, so as people log in during the day more servers are allocated and at night they are released. Typically if you’re seeing this error often it’s due to some sort of man-in-the-middle system, either a firewall or filtering service set up by an ISP/corperation/government that interferes with normal App Inventor operation. The URL above goes over HTTPS and so may be less impacted by the existence of such tools on your network path to Google.
