Today I found that the interface of the academy course has changed, earlier the attachments used to have the right names like “Lesson 5 Practice 2 - Change Font - Answers” etc. but suddenly I see the names are some random characters.
For example - the LESSON 5 – ADVANCED UI INTERACTION - RECAP was downloaded as
95d6ce0a0dab84354c43aaa47892e36f132c16d0.pdf
is this a problem or done for reason or missed in testing before deploying new interface?
