I'm annoyed with Siri and the approach to Timers
I use Timers all the time, especially in the kitchen. I mostly trigger a timer with Siri on my watch. Yesterday I set a timer so the meal I was making could cook for 40 minutes before I added more ingredients.
Forgetting that, and after doing some cleanup, I then made a cup of tea and set a timer for 3 minutes for the tea to steep.
That second timer simply obliterated the first, with no warning. Annoying!
The behaviour I'd expect would be some feedback pointing out I already have a timer with x-minutes to run, should this new timer replace that?
Best of all, of course, would be to be able to run multiple timers on the same device concurrently.

I really REALLY hope multiple timers is coming in IOS 13 but I don't think I've heard anything about it :( I know there are hacks but you shouldn't have to think.

@ChrisJWilson Me too. In the past I’ve been smart enough to set a second timer on a second device, but that's a real pain and shouldn't be required. What really bugged me was that the timer already in place was just obliterated! I gave Feedback.
