Text on Buttons Different in Service (Wordwrapping)

Hi. Let's talk about two things. First, word wrap doesn't mean that will be applied at any size. It means it will try breaking line when the horizontal size can't fit and it HAS vertical size to continue. But if it doesn't have vertical space, it will just show like "word wra..."

Second, I know it sounds weird but after many years I can assume that the size of the canvas at Power Bi Desktop and Power Bi Service is a little bit different. When you are working with the last pixel for showing a word or a number, you can see that it won't work at service. You need more space. You can test this editing the report from service and increasing the size of the box a little bit.

I hope this helps
