Love it, but update threw off HR

Thank you Polar, for the free application and website. Ive used this for two years , and found it very accurate... until the update. Now my heart rate spikes and dips randomly. I purchased the H7 sensor to replace my generic heart rate sensor. This did not eliminate the heart rate variation. I like and appreciate all the other features in the application. Thank you for helping me reach a higher level of fitness. I would ask though please try to discover the cause of the heart rate variation. Thank you.
