Viewers now join free! One subscription runs the whole meeting. MORE RELIABLE IN A FULL ROOM - Sessions with several viewers connect faster and far more reliably; joining a busy session no longer takes repeated attempts - If the presenter's connection drops mid-meeting, viewers now reconnect on their own and keep the deck on screen while they do - Fixed a bug that could leave an active subscription unrecognized, blocking presenting until the app was relaunched - Large decks use significantly less memory during presentations NEW - Share Diagnostic Logs (Settings → Support): export a recent time range and email it to us when something goes wrong. Nothing is gathered until you pick a range, and nothing is sent until you tap Send - The presenter is now warned if someone repeatedly guesses the session PIN ALSO - Sharing multiple PDFs to DeckSync imports all of them - Import problems from AirDrop and the share sheet are shown instead of failing silently - Many stability fixes throughout Terms: https://kojex.net/decksync/terms
