The #37c3 delta chat group has now 48 members, all using guaranteed end to end encryption and several games and apps .... So far without a glitch, no "couldn't decrypt" errors, everything lightning fast, some people using multiple devices with their account, 30 people joining during live onboarding on day1 and using a editor together in the chat (cryptpad without a server basically). Seems like all the milestones of 2023 (guaranteed e2ee, web apps, chatmail) are ... Actually playing out ;)
