I have tried the approaches listed on “Frequently Asked Questions for all DLS Courses,” but still cannot find the submission button. How to deal with this situation? Thanks!
Please check this.
Thanks for your reply, but I have already tried that. The problem remains.
Have you tried to get a fresh copy? You have to rename the old notebook before getting a fresh copy.
Yes I have tried that, and I then pasted everything in the old copy to the new copy.
Can you share the full screenshot of your notebook?
I changed a network and the problem magically solved. Thanks!
Glad to know that…~~~
