iMessages in iCloud not saving space on device
Hi,
I have an issue with iMessages. I have messages in iCloud tuned on and plenty space in the family iCloud drive. As per documentation, this should save space on device: "And since all of your attachments are stored in iCloud, you can save space on your device." Use Messages in iCloud - Apple Support
However this doesn't seem to be the case. On iPhone 11 with 64GB memory the messages are using huge amount of memory (30GB). This renders the device pretty much unusable.
After a wipe and restore the issue is gone for couple days. All messages are available, but only reasonable amount of attachments is stored on device. After a couple days even very old attachments are downloaded and the device memory is full again.
How I expected the feature to work and what I want:
1) message history is available in full, no need to delete old messages
2) old attachments are downloaded only on "request" (specifically opening one..)
Is my understanding wrong? Or is there something that triggers the unnecessary attachments download that I can fix?
Thank you very much.
iPhone 11
