Issue with iPhone as a presence sensor

I have 3 phones set up as presence sensors a Samsung S9, iPhone 6+ and iPhone 6s. The iPhone 6s always shows it being present even when all phones are gone. The 6s is not being sync’d with an iPad or anything else. I have uninstalled and reinstalled the Smartthings app, as well as removing and readding the presence sensor.

Has anyone else seen this issue? Any suggestions?

There are MANY threads that deal with presence issues. If you search you will find them. That being the case, I’ll give you a short answer. Presence sensing within the ST app (Classic, at least) is a hit or miss proposition. Use a third party app like IFTTT.
