症状

Navigating to Confluence Admin >> Recommended Updates Email and un-checking the Send by default option results in no changes whatsoever. The next refresh of the same page shows that this option is still checked.

原因

This could be due to a limitation in certain browsers that prevents the form from being submitted when the option is checked
