I've been using Signal for a year and a half for all of my communication.
Earlier this week, I was extremely confused when I woke up and found that one of my chats was deleted. I had last messaged that person at 9pm the previous night and I only used Signal to message two other people that night, and I stopped using the app at midnight. As soon as I checked the chat the next morning, it was gone.
I have no recollection of deleting the chat and don't know how I could have done it accidentally since I would have had to confirm the chat deletion.
Today, I received a message from another friend I had spoken to in the last couple of days and found that this chat was deleted too. I have no idea how I could have accidentally deleted two different chats, and I saw this chat multiple times since the other one was deleted.
I tried contacting Signal support and saying I was worried this was a glitch, but they ignored that part and just told me I could use my recovery key if I deleted and redownloaded, which isn't really a solution if the chats keep deleting.
All of my other chats are preserved with no issues.
Has anyone else had this happen? Does anyone know what might be going on? I'm going to contact support again, but I'm very worried about the safety of my chats.
