Frustrated with the app's non-responsiveness – Karma | Shopping but better Review

The app is great if it decides to work. I was adding a lot of items to the app, and once I go in there, the items are not there. After doing the same steps several times, the items are in the app multiple times. The app has so many glitches, and it is so frustrating! This almost discourages me from wanting to use it. The main issues are items not showing up in the app, and items being duplicated.
