When I got the HRM Dual I first paired with Strava on iOS. It worked OK.
Then I paired the HRM Dual with my laptop (MacBook Pro). It constantly disconnects only to reconnect few seconds later
Then I tried using Zwift Companion and bridge all BLE connections through the app, and it worked at first but then after a few times it stopped working completely - no app on iOS (Strava, Wahoo, Zwift Companion) is getting the HR readings even though the connection is there.
Any ideas how to fix that?
