My phoenix 6x Shappire does not connect to my apple iphone 15pro garmin conect app

My phoenix 6x Shappire does not connect to my apple iphone 15pro.

Bluetooth is on my watch is in pairing mode,   reset the watch. Restarted the iphone. Uninstalled the app installed the garmin conect app.

Still no luck in conecting my phoenix 6x Shappire to my iphone. It use to work wonderfull.
