Hi @cpradio,
Thanks for the response, appreciated.
That was my feeling. I take it there isn’t anything else which automatically stops the banners?
We typically use them for announcements relating to a promotion, so they have a valid reason for being removed, I have been doing it manually, but when an offer ends at midnight it means I have to stay up! 
If there isn’t anything like this at the moment, do you think it would be worth putting it forwards as a suggestion? No point if you don’t feel it has value.
