Heart rate very high since 5.50

Over the last few weeks, I have got extremely high heart rates during runs, as this caused my VO2Max to drop dramatically I bought a Polar OH1+ optical HR strap a couple of days ago. Sure enough my reported HR dropped by about 30 to 40 BPM and my VO2Max has climbed 2 points in two days.

It is a real shame that I have to circumvent the 245 built in HRM like this. I never had any issues with the optical HR on my 645.

UPDATE 5th Dec 2020.

Although some people don't seem to think it relevant, my plummeting reported VO2Max is what alerted me to this issue as I don't generally obsess over precise HR values and the VO2Max is derived from the HR data. Since 24th Nov when I started using a Polar OH1+ HRM instead of the one built into the 245, my VO2Max has increased from 51 (the lowest I have ever seen) to 57.

In a normal course of events this would never happen.

    is there any chance new updates will solve this? Heartrate detection had been so stable with FR245, but since October last year this stability is gone…. Even easy to measure steady state long runs look sometimes like intervall trainings…

    My heart rate on the 245 has been wildly high. I'm a well trained runner over multiple years who can run 6 miles at an 8:30 pace with no strain.  Running with a friend today at her 13 minute pace per mile my heart rate was showing 160, which is ridiculous.  Often runs will start low then spike high.  It was working but then there was an update and this started happening.  I'm turning off the heart rate monitor and my next watch won't have one.  I can judge everything off of pace, distance and perceived effort better than this worthless heart rate monitor can.
