The details say
We're sorry, a server error occurred. Please wait a bit and try again.
I've been having this problem for hours. I really would like ot be able to tell parents what is going on soon.
This problem happens on all my gradebooks, even the ones where I didn't enter any data since the last report I generate.
Yes, that is correct. Google had issues on their side. Sometimes you just have to wait until their servers are back to work. This should be resolved now.
Looks like whatever problem was happening on the server, it is back to working for me.
Asking about the same problem. Would love some guidance please
