Monitoring two cars, Model S and Model 3

I have been using TeslaFi to actively monitor my S85D Model S since 2016. Last Saturday we picked up our Tesla Model 3, and noticed that TeslaFi picked it up and is recording our drives for the Model 3, but we are not seeing any info now for our Model S, especially recent charging for MS. Any thoughts on why both cars are not being picked up by TeslaFi?
