Kinetic Capsule notification comes before 8km
Turn on adventure sync.
Start a kinetic capsule
Walk 7.1 km
Get a notification that kinetic capsule is ready. But you cant 'claim' the capsule yet.
Restart Ingress Prime
Now you can claim the capsule.
This issue started about 3 weeks ago and is very consistent for me... I get the notification at 7.1km almost every time. Once I had it at 6.9km.
Once I didnt get the notification even at 7.8km, so I went ahead and did the restart of the scanner, and indeed the capsule was ready.
