After installing version 27.09 on my Forerunner 965, the heart rate reads 20-30 bpm high on my runs


unfortunately this has messed up my VO2 max, training readiness, etc since the install.  I’m 4 weeks into a half marathon build and was using the Garmin training coach but I have to ignore what it’s suggesting for the day because everything shows “unproductive”, “strained” and wants me to take rest days.  I’d love to go back to the previous version that I had no issues with.  You can see from the pic above that everything was relatively steady over the past 6 months prior to the install.  Hoping for some solution or a Garmin update coming soon to resolve.
