What's Wrong?

After doing some code research, i had about 4 exchanges on hot to use the app. I close the ap and that conversation is gone. When i asked the app after it happened 3 times, it said it was compression.

What Should Happen?

Compressing tokens should do that and only that, not truncate actual chat messages. Messages should never be deleted.
