Yes, to clarify, Google made a significant change to Android 8, which breaks the existing notification system on the App.
Fortunately, only a few users with high end phones are likely to experience this right now - but Android 8 will be getting pushed out to many more phones over the coming couple of months, so a fix is urgently needed.
As a result of all this, we will moving closer to true "push" notifications. (A few minutes lag might remain though before you are notified of a move)
Edit: iOS will be receiving the same update soon after (Jan 2018)
