[UPDATE: This has been fixed with Sol: Sun Clock 3.1.0, available in the App Store now.]
If you are an iPhone user who updated to iOS 8 today, you may find that tapping the date on the main screen creates a blank dialog at the bottom that may cause the app to become unresponsive. We have applied the fix and are testing the next version now. We’ll have the update in the App Store as soon as possible, but it’s likely that Apple’s review board is super busy right now —yes, they review every update!
The 3.1 update has been approved and is in the App Store now!
