On Oct. 31, 2016 Apple released a software update, iOS 10.1.1, for the iPad. If you have updated your iPad's iOS to this version, then a message may appear when you open the Hancock Software HEAT app that says, "HEAT3.1 May Slow Down your iPad."
Important: This warning message will not affect the performance of the HEAT app or the performance of your iPad, it is simply a message that is shows up to encourage apps to support a 64-bit processor.
Click OK to dismiss the message and continue to use the iPad as normal. The user does not need to take any other action to resolve this issue.
