The list shows up to 100 of the most recent requests you sent or were added to. Several things can explain a request that seems to be missing:
-
The filter. A closed request is hidden while the filter is on Open requests. Switch to All requests.
-
A different email address. A request you sent without an account belongs to whichever email address you gave at the time. Sign in with that address to see it.
-
It is very new. Reload the page.
Older requests are still in the Jira Service Management portal.
