As I posted earlier: This bug is caused by a change Apple has made in iOS 8.3 and has affected other applications as well. We would love to issue a fix, but its not fixable in any feasible manner due to Apple no longer accepting updates using the old SDK which Haiku is built on. Updating to the new SDK requires significant changes to the UI and other parts of the application and would likely introduce a slew of new bugs due to the SDK jump. These are the exact reasons we decided to rewrite Haiku when moving to the new SDKs. At this point Haiku is too far behind to push such a large update. This time is better spent improving the new product.
Update: If this issue was solvable using a simple bug fix, we would have had the update out within a week of iOS 8.3. Unfortunately, it is not that simple. However, we've decided to attempt to move Haiku to the new SDK and then issue an update. I cannot make a guarantee that it will work out, but we will try our best to get it moved over to the new SDK and correct the slider bug ASAP.
Please remember that Haiku is still an older product and all new development will continue only on the Space platform. Because home automation is such a niche, especially in the case of HAI/Leviton -- we're asking for your support by upgrading to Space. With a small user base, for a product like this to survive and for us to keep creating great home automation solutions for the HAI/Leviton platforms: we need your support.
We have a lot planned for Space and the new Server product.
