Power meter (Stages) definitely connected to ZWIFT but 0 power when pedaling

Worked fine this morning, PM definitely connected/paired as I’m getting message that I’m connected and seeing ‘0’ watts in blue box on ZWIFT, but still seeing 0 watts when pedaling. Tried replacing battery in PM but still not working. I then used the stages power iphone app, which indicates I still don’t get power reading when pedaling; has anyone else experienced this and discovered that their STAGES pm failed/broke rather than it being something else? Thanks- ps, right before I was unable to get power showing on ZWIFT, I had just started a ride and saw a huge spike in power displayed, even though I was barely applying any force to my pedals.

ignore post, two hours later all working fine even though I did nothing else
