Hello. Can you tell me why setting the text to the label does not work during the cycle.
Setting the text is executed once after the end of the cycle.
I expect the label value to change on the screen while the cycle is running.
I suppose because App Inventor processes asynchronously. In this case, the for each must complete its loop before processing additional commands.
Place your GetTags outside of the loop and it will display after the for each Block finishes processing
It happens too fast for you to see the change from one cycle to another, so you only see the final output.
If you want to slow this down so that you can see the numbers change, then use a clock timer.
