I was using a Guardian/Simplera Sync sensor and then I changed over to Instinct sensor. I noticed that my graph looks different - why is this happening?

The Instinct sensor sends glucose updates to your pumpp more often than other sensors. If you've used another sensor before, you may notice that your sensor graph looks bumpier and less smooth. You may also see more trend arrows. There's no need to worry! These changes in how the data looks do not change how SmartGuard™ works or gives you insulin. SmartGuard™ still works the same to automatically adjust your insulin and help keep your glucose levels on track.
