Hello, I had this case. When it is so you receive a notification with an error message at the address specified in the setting. In my case, I was not receiving this message because the email address in question was new and misconfigured. Once this problem was fixed, I received the error message and it was a problem of permission of www-data on certain files.
So I suggest to check your emails, check if cron works properly, what you can see in studio => Dashboard => Host Tools => Audit Server.
The goal is to receive the notification that tells you what is a problem.
