However, the display value(icon image) of the "announcement_created_by_you" setting doesn't change accordingly. ( view it from account->notifications) It remains the same icon image before the curl command is executed. in contrary, the display icon of the "conversation_created" change as expected.
We also verify the "announcement_created_by_you" setting does work as API call requests, however the display icon doesn’t show the correct setting. It looks like it is the problem of the display icon.
