Thanks for the tag @IEatBeans. Sorry for the delay. Very long day on the road.
Wyze is aware of this bug. It was reported in the current App Hotfix Release thread with links to the original posts.
A second post was added in that same thread:
This bug affects individual devices with actions to turn notifications on but not groups. It also appears that it is a display only bug and not a functional bug.
When running my rule that contains the “Unknown Device” listing when turning on notifications, I get a successful execution for the rule and a successful execution of the action for every device that was listed as “unknown”
