Disclosure triangle on iOS sharesheet non-operational

This happened before and I thought it was resolved but it came back. When I select drafts on the iOS share sheet, I can share to a new draft just fine. Often however, I want to append to an existing draft, which used to be easy by tapping the disclosure triangle. Now however, the drafts screen disappears and I am once again at the main share sheet. Any suggestions?

This thread is already tracking this issue, if you have any details to add:

I have not yet been able to reproduce this issue on any of my test devices, but am trying to pin down specifics of who might be affected. If you could add details to that thread about what devices/os/drafts versions you are seeing the problem, it would be helpful.
