I have had a response from Apple before too but I think I still submitted way more feedback than I received updates from.Hi Bob,
There are changes in the latest update, build 19C5050b, that may have resolved this issue.
You can see the software build your device is running and check for the latest update by tapping on Settings > General > Software Update.
Has this issue been resolved after installing the latest update?
