You cannot reschedule the countdown timer right after it ends. You must wait a bit.

I will try to find a particular extension that helps with this…

EDIT: You must use a `after x do` block in the awesome timers extension by Daryl. Original forum post link [here](https://forum.makecode.com/t/timers-extension-after-x-debounce-throttle-and-in-background/1925)
