The new update finally lets people turn their texts bold, italicised or strikethrough.
The feature was tested in a beta option but has just been turned on for all users with updates to the iOS and Android app. For most people, those updates should automatically install, and come with version 2.12.17 for iPhones and 2.12.535 for Android handsets.
The feature is enabled not by clicking a button, as on word processing apps. Instead it is hidden in the app, and turned on by including certain characters.
