Hi!
The global notice didn’t show up anywhere.
Oh right I forgot the safe mode before. I just entered safe-mode under various condition set, the global notice shows up. I managed to figure out that it’s the custom wizard plugin interfering. Disabling the wizard plugin brings my global notice back.
Thank you for shedding light on the issue. Though I can’t imagine how can this plugin have to interfere with the global notice… 
@angus Could you take a look at this sometime?
