945 version 2.5 No Longer Recognizes Stryd Power Sensor. The sensor worked fine on the 945 with the original firmware, but now I removed it and tried to repair it to no avail. The Stryd sensor works fine, tested and reset its firmware as well, and retested it on a Polar Vantage and it works. Is this a known issue, how can I downgrade to the firmware prior to 2.48 or should I wait?
