Has anyone had any luck with the opentelemetry tracing interceptor and cron/scheduled jobs.  
We setup the interceptor on the temporal client and everything works as expected (we see all span correctly correlated) for on demand workflow but nothing shows up for cron/scheduled workflows.

Something makes me wonder if the root span is ended correctly. Looking at the source I would assume so but after spending 3 days on this I haven’t had any luck.

I have same issue. When I call start\_workflow, I see the spans, but when I use create\_schedule I only see RunActivity, I dont see StartActivity and workflow invocations.
