USING CHROME

My user, for example, is not creating any events - it's like the Amplitude tracking doesnt exist. I can see this in the Amplitude extension and in Amplitude live events. My user just never appears when I'm using a normal tab.

BUT if I do the same in an anonymous tab and login in my platform, then my user is tracked. 

I don't understand if this is related to cookies, but it shouldn't be. My trackings always work in the Amplitude websites and in the other platform that I used to work on. 

Why is this now working? I'm afraid I'm missing other users' trackings. Like, this is literally happening, because a client sent me a screenshot of their screen when they were using our product, but they werent showing in the Amplitude events.

But again, I can't understand why some doesn't work. I can see events being generated for some users, but I know for sure that we are not tracking all of them.
