I have multiple users who have selected to watch a high profile page to receive the updates. They have have noticed on multiple occasions that they have stopped receiving emails. They go to their My Watched Posts page and find that the email notifications for that page have been disabled. This may explain why some other users have claimed to not receive the email. Is there a limit to the number of people who can watch a page or the number of emails that can be sent? Any help is greatly appreciated.
