Week 1, part "Understand what you can automate", assignment Roboth Path: Cannot select transaction # from DoubleUI app

Hi everyone,

I am stuck here (sorry, UI Studio is in German but I guess you’ll get the problem anyway):

When using “Get text”, I cannot select the part within the app screen which I would like to extract, which is the transaction number. I cannot select by myself via F3 either.
I checked other available actions but none of them seem to be correct or work for me.

What’s wrong, can you help me?

Thanks & kind regards,
