Siena Trigiani welcomed attendees to the first Tech Extravaganza 2.0 and announced a permanent transition to Zoom for all future sessions, effective August 20th, due to Google Meet issues, a move supported by Ali Moosa for its robustness and integration. Siena Trigiani then conducted a comprehensive tutorial on WhatsApp, covering features like status updates, editing “About” information, composing and sending messages (including dictation and reactions), sending stickers, and initiating voice and video calls. Discussions with Ali Moosa, Ivy Matouk, and Jeroo & Lionel Russell clarified WhatsApp’s privacy settings, its universal compatibility compared to iPhone-specific apps, and how it utilizes the Call Kit framework for ringtones.
