Frequently asked questions
Do I have to use the app to join a Blitzz call?
No. Most calls work in the browser. Use the app if the browser connection fails or you need app-only features.
Do I need to type the session code in the app?
Usually not. Tapping the SMS link after installing fills in the 9-digit code for you.
