React Pomodoro Clock problem

Tell us what’s happening:
Hello,
I’m working on building the Pomodoro clock and am hitting a road block. I think I’ve been staring at the same set of code for too long.

As far as I can see, everything seems to be working however when I run the FCC tests I can only get to 20 / 29 and I can’t seem to figure out why it’s not working / passing.

Any help or advice is greatly appreciated!

I figured it out. Trying to convert minutes and seconds to a single time left value and then back to minutes and seconds was causing a weird delay. To any who saw this post and tried to figure it out, thank you in advance!
