I had this working before, but not now. How do I change the size of the text to be smaller for iPhone layout and larger for desktop layout? This text is in a global.
Looks like there’s something wrong with my text block in my global. I tested with a fresh text block and that worked. I’ll work on this again this evening.
I have it working now that I replaced the corrupt text block. Yikes!
Glad you got it working. If you managed to break it again can you share the project with us so we can fix the bug! 
This happened again this morning. I could not change the text block attributes by just selecting the text block, I had to select the text inside the text block. I created a new text block and that worked. I cannot figure out why this happens.
