Locate My Participation Threads in Apple's Support Communities

I do I find the threads that I've authored?

When I click the My Subscription link, it indicated "There is no recent content available." I'm not sure how Apple defines "recent", it's been 6-8 months since my last post so I guess it's understandable nothing is listed under this tab/section.

I then select the Participation tab and it indicates: 4 Participation in Threads. That count (4) seems correct. I assumed my threads would be listed in this section, but it's not the case. Other than telling me how many thread I participated in, it's very not helpful. It would be nice if my threads where listed here so I could easily refer back to a given thread/question. All my threads/questions have been in the Apple Numbers Community.

I tried using the Search > Filter > Author > username (to limit only threads based on my username). But I received "There is no recent content available." message. Again, I guess key here is recent.

I then used Search > Search communities and people > entered my username (no filters applied). There were 600 results, I went through each of the 600 threads, but there was only one thread that I authored listed in the search, and it's not the one I needs.

I'm not sure what I'm doing wrong. I'm looking for help/suggestions on how I can find my 4 threads/questions that I've asked?

Thank you
