This is an AGO-hosted dashboard. I see this happen in both recent versions of Chrome and Firefox. Our local news had our dashboard up on their screen last night and the numbers were cutoff
That's heartbreaking Mike
Only other guess might be any formatting tags you have for the display/font which might mess-up the auto resize? If so maybe select the font and colour from the options instead.
I wasn't going to post, then saw it was you, Mike! Hi! I am running into the exact same thing. That is supposed to be a "d" at the end of Captured. It looked fine when I configured and even when I opened in my AGOL organization. When I open with https://www.arcgis.com... it gets cut off. I tried different font sizes, even adding a blank space after the text. No luck. I haven't contacted support yet.
I had luck with this: Turn on advanced formatting. Add an underscore and a space after the text. Save. Remove the underscore. Save. Then I refreshed the app and the alignment was fine. I see on your example it's the number rather than the text. Maybe try adding some blank spaces at the beginning and end of the titles to make them wider? topText: ' Tested ',
