On Pico WebIDE Connect - Unable to retrieve board information. Connection Error?

Why doesn't the last saved file get loaded into the Right-hand pane on relaunch, . . . . Everytime?

It's a restriction of the Chrome Web App unfortunately - it's very hard do do anything when the app closes - so you either have to save every change (in which case Google has a limit to the number of saves to cloud storage) , or every upload - which is what I have been doing.

The new IDE code should help with this, but that's not live for Native IDE and Chrome Web App user yet.

Could you upload the exact code file that gave you the upload error please? Then at least i can try and figure out why it is breaking.
