Android EBC + Stages SB-20 auto power not controlling well

I did an endurance workout last night. Running EBC on my android phone (Pixel 7). Simultaneously watching Xert videos on an i-pad with bluetooth headset. I did the workout in Auto mode.

There were two issues I ran into:

  1. At the start of the workout, the recorded power would occasionally drop to zero then come back again. I didn’t notice any change in the resistance, just slightly annoying visually.
  2. In the second half of my workout, the Auto mode stopped controlling my resistance well. I was maintaining a fairly stead cadence (low 90s rpm) but the resistance kept varying between the low 100s to mid 300s, while the target resistance stayed fairly constant (see picture). I felt this, and it made the workout really frustrating, although because the spikes were short I was still able to complete it.

Any suggestions on a more stable connection to the SB-20? I could also run EBC from my iPad, although I’d prefer to view YouTube or the player app on the bigger screen and run EBC from my phone.
