Android primary, iPad and desktop clients linked. Comically, every platform has different issues with "deleted" meta-info popping up again. Like "deleted" groups, "deleted" contacts, "deleted" chats... meta links I can't get rid off whatever I do. The worst is legacy groups I left, "deleted", can't even use or join anymore, but also can't get rid of. They reappear every time I refresh the iPad app. Mind you, the group members are still visible, so I am really happy whistle-blowing, terrorism or crime isn't my profession. This made me really distrusting of Signal, when years old meta data popped up again. Like, have they lost some pointers or something? Can I even expect the data to be gone, when I delete my account for good? Doesn't feel like privacy at all...
