2 iphones getting the same messages
Wife got and iphone X about 2 years ago and I took her (don't laugh) 5S. Everything was fine til about 2 months ago, maybe after an update when we started getting same texts from certain people. Both phones have same Apple ID, wasn't a problem before. First time it happened I believe was fixed by changes to the cloud. Now not sure how to fix. Was told only way to do it is a separate ID.
Any ideas are appreciated.
