Heart Rate monitor disconnect during FTP test


I have done twice now the FTP shorter test and both times exactly 10min into the effort my heart rate sensor disconnects. I’m using Polar H7 with Zwift Companion on android and running Zwift on PC. It can’t be a coincidence that the sensors stops working exactly 10min into the effort twice.

Have anyone else experienced similar issues?



There has been some issues with Android devices not being able to pair BLE devices : https://support.zwift.com/hc/en-us/articles/213614686-Some-BLE-Devices-can-t-pair-over-Android-ZC I have provided a link to an article on our knowledge base that will further explain this.
