Since the update it's been unreliable. Takes ages to load, even maps I've previously downloaded. They push user maps too hard without ways to filter them out or get rid of redundancies. If I'm out on the hills and want to see some trail options, I'll be there all day staring at a blank screen before realising the app has crashed again. Would prefer less options and a more functional app!

Not a fan, especially as it decides to randomly log me out whilst using the app. A bigger issue for me is that when I look at my route after I've been out, it looks like I've been through peoples houses! If I've walked in a straight line I would expect to see a straight line on the map. I can't believe the distance covered because of this and generally reduce it by 20% .

Lots of bugs. The app always tells my my altitude is around 50M higher than it is. Other apps on the same phone get this right. The time a route is expected to take shown on the app is different to the same route on a PC (is it failing to take into account customised activity speeds?). A route that has been edited on the app still shows the old route image in the list of routes.
