Wait instruction in a loop
I am aiming at updating a label every seconds but the rendering is always made at the very end of the loop.
Using the https://m5stack.github.io/UIFlow_doc/en/en/Start_programming/Wait.html I was hoping this type of loop would to it.
Is there anything in particular to take into account?
A specific button calls that function, the rest is pretty simple a label being displayed on the middle of the screen.
But instead of seing, 1, 2, 3,....10
Only 10 is displayed at when loop has completed.
