If iOS is crashing on 2.14.0, please check if you have an incorrect type set for a multiAttributeTile in a custom device handler. Here is an example of incorrect code
tiles {
multiAttributeTile(name:"contact", type: "contact", width: 3, height: 2, canChangeIcon: true){
tileAttribute ("device.contact", key: "PRIMARY_CONTROL") {
attributeState "open", label: '${name}', icon: "st.contact.contact.open", backgroundColor: "#ffa81e"
attributeState "closed", label: '${name}', icon: "st.contact.contact.closed", backgroundColor: "#79b821"
}
}
Changing the ‘type’ from “contact” to “generic” should resolve the issue. We are also looking into fixing the app so it doesn’t crash with an incorrect type. On Android, this seems to manifest in a “?” tile.
