I regularly ride my trainer (Saris H3) using my Edge as a control. I save routes I have ridden outdoor and "re-ride" them during the winter on the trainer. When showing the map screen, the top bar shows upcoming road crossings and they are always wrong. It almost always indicates upcoming roads that are close to my home, even when I am very far from that on the route. I don't know if this was a problem before 26.17 but I didn't notice it until recently and on different routes. It's not a big deal, as it's only cosmetic. As far as I can tell, the resistance for climbs and descents is working as expected, which is the important part.
