I want to keep all my timeline history backed up, but don't have that cloud icon there. I thought the issue might be that I need to update Google Maps, but I did and it's still not there. Can't figure out how to keep it backed up. (This is on an iPhone 13 mini.)
Separate issue which I've had for a while is that I have a bunch of years of timeline history (which I like having) on a google account that I don't use much anymore. I wish there was a way to transfer it, but I've searched a few times over the years but never found a way to move it between account.
