I'm not the first to ask this question but the answer given previously pertained to the website in a browser not the new app. I'm happy that there are people in the world with good enough eyesight to tolerate the tiny font size but some of us have older eyes.
I’d like to thank you for taking the time to come and let us know your thoughts here on the Community in regards to the new desktop app. Currently we don’t have the option to change the font size within the app itself so I’ll be passing along your valuable feedback to our dev team for review.
Sorry I can’t be of much more help here, please do let me know if you have any other questions or feedback - Thanks!
