Crashes quite frequently in iOS 9.3

Why does the IFTTT app on iOS 9.3.2 take up 1.3 GB of storage on iPhone 6s? What is it storing?

Warning: Very unstable on iPhone 6s running iOS 9.3.1

The latest version is still not working properly. Launching IFTTT from the iPhone 6s Notification screen will erroneous launch IFTTT in the home/summary view instead of the specific notification item that Im interested in seeing. Please fix ASAP.

(Below is my previous comment.)

IFTTT is a good app. Unfortunately, on iPhone 6s running iOS 9.3, the latest version crashes quite frequently.

I have set up 30 or so IFTTT rules. Most of my rules are set to send notifications on my iPhone 6s.

Notifications appear when my phone is in the lock state.

When I swipe one of the IFTTT notifications from my lock screen, many times it will launch IFTTT app and then either hangs or crashes outright. Very frustrating!

And once I swiped the IFTTT notification from the lock screen, it is removed from the notification list.

So, if a crash occurred, my notification is gone for good.
