Can’t personalize a trip

The app itself isn’t bad, but when logged in and trying to edit favorites, it says update failed. I can’t store my favorite destinations or get the custom trip report as advertised. Deleted and re downloaded and still have issues.

Used to work great

I got this app for winter driving information. Ever since the last update that is the information I cannot get on the app. Some of the time the option is available in layers but if you click on any other option (like plow information) it disappears and you have to completely reload the app to get it back. The app is useless if you can’t get the information you need when you need it most.

Great WHEN it works...

I use this for Iowa winter driving. Recently the winter driving does not show up at all. One hour commute to work on county highways and now it only works half the time. Last season I never had a problem. Hope they get it fixed.

Developer Response ,

Hi! I’m sorry you’re experiencing outages. Unfortunately we (Iowa DOT) don’t report road conditions on County roads - only the roads we have jurisdiction on (Interstates, US and IA highways). Also this app requires an internet connection, so if you lost your internet, it won’t be able to load the road conditions.
