My Fenix 5 plus updated to firmware 4.00 in the morning. I can't find the changelog yet.
(GPS, WIFI, Sensor Hub have same ver. as 3.56 Beta) ciq.forums.garmin.com/.../1387081.jpg
I just spoke with a Garmin rep., and he explained that they typically roll out a new update to about 20% of registered users per day. The 4.0 firmware update has been pulled for now because some of those who first got it reported problems. He anticipates that it will become available again within a week.
What a mess and unprofessional software development/management at Garmin - really the worst i ever experienced!
That funny "20%" guinea pig method is a testimony for "ahmm... we don't exactly know what we are doing, so let's only infect 20% of our customers with the new firmware-experiment so that we don't have to exchange 100% of the delivered watches".
4.20 is out, I never even received 4.00.... :-D ok, keep waiting for the percentage to grow on that rollout counter....
