My trainer connects all good at the beginning (not as a smart trainer, only as power meter) on my Mac. But during my ride my power meter connection will drop off and reconnect after a few seconds. My cadence and HR will also intermittently drop off as well. Anyone else with this problem? BTW, I have all the latest iOS releases installed. Thanks!
Are you using Ant+ or BLE?
If you are using Ant+ a USB extension that puts the Ant+ dongle near your trainer could resolve your issue.
