Time will fix it, haha.

It still hasn't updated so I think it doesn't work 😁
I just tested it locally by setting the expiration time to 1 hour. It does clear expired cache and re-fetches when no cache is available.
The cache cleanup only happens one minute after opening the page, so if you haven’t used it for over a minute, it won’t trigger. Also, if you keep the page open, it won’t run the cleanup again.
Odd. So I open the relay page and then use it for more than a minute?
Not the relay page, just keeping Jumble open for a minute will trigger the cache cleanup.
