Deleting large attachments when iMessage is set to save to the cloud
First, forgive me for asking a question that has probably been asked so many times before. I have Googled it, but it's tough to find this *exact* scenario.
I have an iPad and an iPhone and both are set to save iMessages to the cloud. My understanding is that this makes it so that iMessages are pulled from the cloud to either device, and thus do not take up local storage. However, I still have the option to review large attachments on each device. Are these attachments stored locally? Or when I delete these attachments, am I deleting them from iCloud?
In other words, if I delete the attachments in "review large attachments" on my iPad, will it also delete from my iPhone, if I have iMessage set to back up to iCloud?
Thank you for helping me wrap my head around this!
