I read that 5.21.3 fixes Iphone - Garmin Connect Pairing. But, I still have an issue as it only "half-pairs for me".
After deleting apps including Garmin Connect Iq, reinstalling and ensuring Edge is removed from iphone, + restarting all devices and turining iPhone BlueTooth on/off.
Garmin Connect on iPhone initially recoginizes Edge 530 and gives pairing codes on both devices indicating connection. However, then Connect goes back to complete pairing and is not able to find the Edge 530 again. Despite multiple tries and the claims "of extended search" it never finds the Edge 530 again. Edge 530 goes back into Phone Setup mode wailing for iPhone and Garmin Connect on iPhone says "no accessory found" (despite just fnding it a few minutes ago and getting correct pairing codes on both devices.
The 530 then appears in Iphone as Bluetooth device and Garmin Connect with red circle indicating pairing process not complete.
Have deleted it in Connect and iPhone Bluetooth several times, but cannot get by this 2nd pairing step.
Garmin are you going to fix this issues and QA that it is fixed? The extended accessory searching seems like a bandaid.
However, I am able to successfully pair my Forerunner 645 watch with iPhone and Garmin Connect so it appears to be an issue directly with Edge 530 and Garmin Connect app.
