Here is my problem :
I'm creating an app for tennis table scoring and when I click on the start button of my app, a notifier opens on the new screen to know who of the 2 players will start the match (The 2 buttons on the notifier are the 2 names of the players).
When I click on the first button of the notifier, my program works perfectly on my phone.
However when I click on the second to show that the second player has to engage the match, a part of the program do not work.
Do you know where is the issue ? (check the 2 screens)
