Synced photos filled storage
I had over 5500 photos on iPhone and over 5000 on iPad. Somehow they have merged so I now have the same 11,000 photos on both which has filled the storage on both devices. I have used the same Apple ID on both for years but the photos were always separate before (even though calendar, notes and contacts automatically synced).
What have I clicked to do this as I’m scared to muck about with settings incase I lose anything but I can’t have the storage full on both. Thanks in advance for your advice.
