> Yes, Proton Drive eats 400 GB of your iPad storage now, I don't know how to trim that regularly.

I love Proton services and have been a subscriber for years. I do not understand what is going on with this. I have proton drive on my iPhone, I manually open it monthly to let my photos sync. I pay for the storage on proton drive to _save_ space locally, but whenever I sync to proton drive the storage space used locally by the app is almost equal to a local photo library! Yes I can delete the app, re-install it monthly to sync my library once, but it quickly balloons to dozens of gigabytes when I start to sync my local photos.

Can anyone at proton explain what is going on here?
