Every time I submit a tracking number, the LastPass app thinks I've inputting a password and prompts me to save. I will never want this.
Thanks! I looked in my app settings a bit more and found a list of apps where you can select "Do not show fill window". Oddly, the app I'm trying to set this for doesn't show up in the list, but many other mobile apps do. Not sure what's going on there but at least it's possible for most apps.
Maybe this?

(I admit, I'm not sure exactly how to identify the URL that sites behind an app autofill in the mobile experience. I've seen the same problem you've described, and yeah it is a real nuisance.)
