I don't think Lionel is under any fantasy to think they won't be squashing bugs for a while. They only have access to so many types of devices, resources for testing, and real world experience is always different than testing in a controlled environment. Right now IMO the BT seems to be an improvement of the LC app despite some of the issues.
I would suggest we comment on what we find and let them sort out the issues.
I would also suggest checking to make sure the app you are using is the most up to date version and include that information as well as the device type you are using, engine w/ product number, and any other perinate information to help the process.
The more information you can provide the quicker a solution can be made.
