Just to make sure everyone understands... Forgetting about Hubivue for the time being, if you bring up the list of Devices on your Hubitat hub, do you see both of the Life360 Presence devices, one for you and one for your wife?
If both are still in the Hub's device list, then the title of this thread may need to be changed to make it clear that the issue you're experiencing is only related to the Hubivue dashboard tool. If this is the case, then I would recommend asking this question in the Hubivue community developer's thread as you'll receive much better support.
If the Hubitat Hub no longer has both of your Life360 devices in its Devices list, then that is a different issue.
