RE(urgent): The case of vanishing projects

Hello. I'm a young and enthusiastic new app inventor on your platform. My issue is this. I have tried creating an app twice; twice I have saved my projects, and alas! Twice those projects have vanished into thin air on my PC! I can still see the project on my companion app, though it's unresponsive.

Of course you can see my need and urgency for texting because I cannot continue creating the app before we solve or fix why they keep disappearing.

Please help.

Can you provide some more information about your project?

They're not on your PC. They're stored on MIT's servers under your login ID.

If you entered without logging in, they are under the re-entry code you should have saved.

I can see the project on my companion app, and it loads perfectly, but on my PC where I'm building it on (yes, I logged in and can even see the project listed), all the code is gone; it's like a blank slate.

Simple educational app: i had built all the base code; all that was left was to insert text, it still loads on my companion app, though. The only problem is when i log into my pc which is where I'm creating it, it doesnt show

How are you logging into AppInventor (google account) ?

Which server (url) are you using?

Could you be in a different Screen?

Try a right click Cleanup Blocks in the Blocks Workspace to pull all of the blocks together.

That's a built copy, not the original source.

It's a good idea to periodically export an aia file from your Project, and save it somewhere safe.

I do that for every project I build, after every hour of work.
