Can't use backup from icloud on new phone because IOS 12.3.2 is not available
My previous phone is an 8 plus, updated to 12.3.2 My new phone is an Xr, which can only update to 12.3.1. From some quick research is seems 12.3.2 is only for the 8 plus so I can't see it for the Xr. I don't have any previous icloud updates, I only created one now for the purpose of transfering to my new phone. My new phone cannot use the old update because the IOS are different. Any suggestions on how to work around this, or dial back my 8 plus to 12.3.2, or get my Xr to 12.3.1? Thanks
iPhone XR, iOS 12
