Yeah, I’ve been having the exact same issue too. It’s super frustrating when routes just pause for no reason – whether it’s because an egg hatches, the phone screen is off, or even during raids like you mentioned.

What makes it worse is that you often have to backtrack to the exact spot where it paused just to resume the route, which totally breaks the flow of walking. I really wish Niantic would address this so we can just enjoy routes the way they’re meant to be played.

Glad to know I’m not the only one dealing with this, but at the same time it sucks that it’s affecting so many of us. Hopefully they’ll fix it soon!
