Adsense ad unit status
Did you create a new AdSense ad unit and does it still show the status as New after a long time instead of showing as status? Follow this thread to learn more about it.
When we login to our adsense account. We can see 'Ad Unit' under 'My ads' option.
In my case, STATUS of 'Ad Unit' is showing as 'NEW' and only few are 'Active'.
