Hi Tatiang , I try to explain my problem. I selected exactly the right circle. At the beginning ,for each circle button, I had background color blue. In the block I used function "Button TOUCH UP - TOUCH DOWN " selecting 2 different pictures for UP or DOPUN . When the App was running , the first picture displayed was the 4 button with blue color . once I touched each button the right button picture was displayed. to avoid this issue, Instead to have background color, I selected background picture and i used the same picture used in the block for botton “Touch UP”
this s the picute as I touched all 4 bottons
this is the picture as I replaced the blue Background with the picture
this is the picture of the app as is displayed to my phone with LIVE TEST ON DEVICE
this is the picture of the App downloaded to my phone while the app running
this is part of my block
