Hi Sayn,
Yes that is expected. The countdown timer is in a different column. So on small screens it switches back to a new line.
This is designed because, most users have long message hence it makes sense to put the timer on a new line. Otherwise it will look ugly.
If you want to show in same line, we can do it via CSS. Please share the page where the announcement is added, I’ll have a look and suggest the changes.
Thanks,
Aakash
