Re-pair Apple Watch to iPhone after old phone restore
I had an Apple Watch Series 1, paired and works no worries. I've created a backup of my phone. Then I've got an Apple Watch Series 6, paired and works no worries. I have backed up my phone, but apparently that backup is corrupt or something, just reboots the iPhone when I try to restore the backup. My phone got reset this weekend, and after a painful few days I'm back up and running again - but using the backup that knows about the AW1 but not the AW6.
I can't put the watch into pairing mode because it knows its already paired. How can I get my AW6 back onto my phone?
I've tried the force press as mentioned here: Re-pair Apple watch after iPhone reset - Apple Community
, but it's not working, no option for Erase.
