My Wife has recently started to become a follower rather than friend on the app. We have tried everything to sort it but sometimes after a minute or after an hour or 2 she reverts back to a follower on my phone and I need to re request. If I go in to settings on her iPhone and her iCloud then under family sharing, my name is greyed out and says cannot see your location? No idea what has gone wrong and I think it has only started since she got me an Apple Watch for our anniversary. Any ideas?
