Hello,
I'm pretty new to all of this so I apologize if there is an obvious solution. I created a simple map of some routes and tried publishing as a web map, when I look at the map online, I cannot see the routes in detail, they are very blurry. I assume this is an issue with the scale of something, but I am lost with how to fix the issue. Here are some screenshots of what I'm talking about.

Thanks very much!
