No reaction on controls since last app-update - Solved

Today I realized the sketch I was working on for a long time suddenly did not react anymore on controls. I found out this was an issue that came up with the automatic blynk app update to Version 2.5.9 on my iPhone 5. Finally I found out how to solve the problem. I had to touch every control element in the project settings.

Thanks for the report. Can you specify what controls stoped working? Anything except button?
