I am new to Blynk and am writing a sketch to control neopixel strips with a menu system. I followed the code example but my sketch kicks out after each selection instead of staying in a loop. I know I am missing something simple, I just cant see it. The code isn’t long as most of the menu options have not been filled out yet. Thanks in advance for any help. - Jeff
