Garmin power pedal connecting but not showing power

I use the Rallly RS100 power pedals and they were working fine. I changed out the battery and now it’s connecting easily but does not show any power reading. I had to get up to 100 rpms pushing hard to even get to 30W. What points me back to Zwift is that I can use it on my road bike with my Edge computer and it works fine, or at least is presenting reasonable data. I am trying to connect on my iPad and getting these results, but have also tried on my Macbook with the same results. I have also removed the battery with only the iPad nearby and reconnected a couple of times with the same result. Any thoughts?
