Yes the app lets me see information about my license and car registration, all of which I can see if I look at the actual license and car registration - honestly much easier to pull out my wallet or look at the windscreen. . It doesn’t let me do anything that useful like pay a toll.

Thanks for taking the time to send feedback. We will be adding more functions and features over the coming year - for example adding toll functionality is on our backlog of changes. Thanks for your patience with this.
