Hello Ken,
In your original method, did you set the color of the text to be different than the color of your background? I wasn’t sure if this is something you found out accidentally using my method or if it’s something else.
I also tried replicating your method, and I am unsure why it doesn’t work. I tried accessing the labels through an external variable, in a spreadsheet, but nothing seemed to work.
It seems like updating the label after initializing it is problematic.
