This is a problem I had several times with the betas, and now it showed up in 21.16. A quarter mile into my ride today on my Specialized Turbo Levo eMTB all sensors dropped. After I stopped the activity and did a power off/on, they reconnected and everything worked properly for the next 1 hour 50 minutes. I had this happen during the beta track for 21.?? several times. I attach the zipped FIT file for the part of the ride up to the problem. I have a limited ability to read FIT using perl's Geo::FIT module, and it looks like the dropouts occur at 2024-05-25T13:43:54Z. Sensors paired are my HRM Pro+, a Tempe, a Varia RTL515, the Turbo Levo as speed/cadence, power, and e-bike. I use the Windfield.app, MyBikeRadarTraffic, and Strava Relative Effort ConnectIQ fields.
