I ran into issues, as have many, many others. For awhile, I used ST phone presence and Life 360 in tandem. Using both together worked great. About a year ago, I reviewed everything and found that Life 360 was always working perfectly for both my wife and I. We have a mixed marriage, she is IPhone, I am Android. Since then I have used Life 360 exclusively for presence both in Michigan and now in Florida without any problems.
