This should get you there, I added the second level of the class .new-user-summary to reduce likelihood of impacting other areas, but should still be checked:

.new-user-summary .coach-share-overview, .new-user-summary .report-courses-summary {
display: none;
}

.new-user-summary .coach-share-overview, .new-user-summary .report-courses-summary {
display: none;
}

Thank you @Bfarkas! You are a hero! 

@Bfarkas … a follow up question for you if you have a moment. I have been beating my head on my desk trying to figure out how to isolate and hide these two elements in the “Report New Training Activity” area in My Activities. I know it is possible, I just can’t quite figure it out. Any pointers? 

So I thought I was nuts for a second cuz I thought this exact thing had just been asked last week, but different fields:

anyways, did not actually test as the same theory should holdup:

.control-group:has(#TranscriptsRecord_score) {
display:none;
}

.control-group:has(#TranscriptsRecord_credits) {
display:none;
}

kept them separated so you can always swap easily.

AH! I see the logic now. Thank you so much, @Bfarkas! 

.new-user-summary .coach-share-overview, .new-user-summary .report-courses-summary {
display: none;
}

Hi there, I’ve tried this and it’s not working. Any ideas of what I could be doing wrong?

.new-user-summary .coach-share-overview, .new-user-summary .report-courses-summary {
display: none;
}

Tough to know without any insight into what you did. It is usually a typo or something incomplete somewhere in your block of CSS
