The app has so much glitches

I am using this app for more than 10 days and I noticed it to be having so many glitches. Especially, when tracking and also, sometimes it shows a different products pics which doesnt belong to that product. I hope you will fix it soon. I am giving it 4 * because, the live chat option is great with a quick, responsive and kind assistants.
