Lagging tracking, would never locate my position on map, legend seems like it was made in 2010

This app worked really well for tracking my friend. Never used it before 2024 so can't speak to any previous issues in prior years. But for seeing my friend almost exactly where he was on the course and planning to meet at certain spots, worked great. Real time map feature was perfect. Thank you! Also, he didn't need the app as a runner but it differentiates between runner or spectator, not sure the exact differences but thought I'd mention that.

Mildly helpful for seeing the route I guess...wasn't even available until a few days before, lagged a bunch with tracking our runner, and only a few CTA stations nearby were marked, so I had to use several apps at once to help me figure out where to go (really annoying when you're trying to track quickly in a race). When you zoom in on the map, it doesn't let you go far enough to see street names quite often. Thankfully our runner had downloaded a phone tracker app, which was much more accurate!
