🤖 You can now choose your message text size. On a computer, open the menu →
Theme and drag the new **Text size** slider — the default is now the same
comfortable size iMessage uses on the Mac. Using the web app on an iPhone or
iPad? Messages now follow your system Text Size setting (Settings → Display &
Brightness → Text Size), so if you use larger type, your chats do too. The
iPhone and Mac apps pick this up in their next update.
