compilation failed. please report this issue on our forum

this keeps happening with every sketch, it doesn't save anything after a while, so all is lost.

Sometimes there might be a temporary glitch that is fixed after a short while. I just tried a compilation with Arduino Web Editor (I don't own a Chromebook so I can't test the app) and I had no problem. Please give it another try now and let us know if you still have the problem.
