My kinetic capsule still says 4km instead of 8km and it does not count progress towards completion. It has been that way for several months now. (2.84.1) is the version of Ingress i am running on android 10 with an LG K92 5G on a 5G and wifi signal.
Sorry about the delay, @Gaberidine! Please let me know if you are still having this issue. If yes, I'll share it with the team to look into it.
