After this #MobileCoin story, I decided to delete Signal and find a really safe and private alternative, but at the same time as user-friendly as possible.
@TheFuzzStone I think the problem is that it doesn't allow offline messaging due to its decentralized nature? Both sides have to be online at the same time in order to deliver messages.
@gandalf86, I once tested Jami (then it was still called Ring in 2016-2017) and you're right, then you had to have both contacts online.
Now, it seems to me that you can send messages offline and the other side will receive them when they appear online.
