I’ve encountered this situation 3 times recently. The first was on I-70. They closed the whole freeway due to a car fire and rerouted traffic. The app would not allow me to select the correct closure and only allowed the offramp to be selected. It took hours before the closure somehow showed up on the app. If other Wazers could have reported it accurately, it could have saved me hours of a delay.
Then, in town for construction closures, I’ve also encountered the arrows not popping up in the correct location. It should be easier to select the closure area and even mark the distance of the closure if known.
