Messages deleted on Mac are not deleted on iPhone and visa versa
I was running out of space on my basic 5G iCloud acct so a friend of mine suggested I no longer "store" Messages in iCloud but only use iCloud to sync them between my devices. I argued that if I disable Messages in iCloud, it would not sync between devices but he insisted it does and that is how his is set up.. ..ok, so I turned off Messages in iCloud on my iPhone and Mac.
I swear a day or so after doing that, it worked just like my friend said in that when I created and sent a Message on my phone or Mac it showed up on both devices and when I deleted a Message on one device it immediately deleted it from the other device but now, a week later, it's not syncing between my devices when I delete a Message but it will add a new Message on both devices when creating it on one. I have signed out and back in on both devices, didn't change a thing.
When looking on line I couldn't find anything definitive that separated the ability to sync between devices vs storing all my Messages in iCloud. I prefer not to have my Messages stored in iCloud but do want the syncing benefits both ways, adding and deleting. Is this possible?
