The popular messaging app Signal is currently experiencing server issues as reported by multiple user on X (formerly Twitter) and multiple sites such as downdetector.com .
So far no statement from Signal themselves, and their status website https://status.signal.org reports “Signal is up and running”
I thought the goal of the username was to also have the ability to use Signal without any phone number at all
Nope, you still need a phone number. You just don’t need to give the phone number out to contacts you want to talk with and can instead use the username.
Ah yes, I see that now by ready the blog post more carefully.
