Thanks for your response. I don't know if this question got thru when I marked the response as acceptable, so I will just say TIA and ask again. What is the cause, and how do I fix/remove the following warnings that are popping up when the app is run in developer mode in code? Error follows: This method should not be called on the main thread as it may lead to UI unresponsiveness. This method should not be called on the main thread as it may lead to UI unresponsiveness. (about 7/8 of those lines) end of errors. Your insight would be welcome. Thanks again.
