Question: optimise storage on yet iPhone full
My Photos library currently contains around 19,000 photos and 1,000 videos and takes up 160Gb space in my iCloud storage and on my MacBook Air where I download all originals to. I love having all my photos on my iPhone 6 (16Gb) and so have iCloud Photo Library enabled there too with Optimise iPhone Storage enabled so only low quality versions of photos are stored on the phone.
As Optimise Storage is enabled I would expect that, as per the name, the storage on my iPhone is managed so that it doesn't fill up completely and that if I want to take new photos / videos the phone will allow this however this is not the case. Despite having very low quality images on the phone when I take a short video the phone fills up not allowing me to take more.
Please help with how I get iCloud to manage the storage better so that I can still use the camera on my phone while still having all my photos on my phone.
