Hi, your change that the email Ad Appears as a "not read" Top email at inbox -it is very disturbing.
you are impacting your users for the advertisements.
if it will continue this way - i will move using my gmail account which i avoided using for years.
today my gmail FRWD all content to my yahoo emial and my yahoo email is my main account and app im using.
im sure there are many users who think same way.
good luck.
