I’m just about done with Garmin Edge 25 and iPhone. I can’t get this device to consistently connect through blue tooth

I’ve had it. I’m tired of spending 15 minutes after every ride trying to get this device to pair with my iPhone. Today I had no success at all. Can’t use Strava because of that. I’ve read the discussion boards on the issue and I am just frustrated that every si le time I sue this device I have to waste so much time getting it to perform the function it was purchased for.  Kinda feel like I’ve thrown away a couple hundred bucks. Lesson learned
