Awesome to use Signal not Telegram for group chats, but when I select the link to cipy and move it to my profile with Signal it takes me to a screen that says "This is not a valid Jabber ID".
"Freedom Tech" Signal group just hit 200 members!
Ironic that Trump's Signal blunder, has been increasing popularity in the platform. While it is centralized, SimpleX/Session have less ways to filter spam.
Come join the fun, you can ask questions on Linux, Phones, which privacy services to use, how to use cryptocurrencies such as Bitcoin/Monero, what vendors accept it, how to setup a website, and more.
We provide some Linux/crypto tech support in the chat, and other members contribute. So this is a good resource to have at your fingertips to pop questions. I bet you'll join a novice.. but in a few months, you'll be the one answering other people's questions:

Note: We are a VPN provider, so please avoid promoting direct competitors. I am volunteering to provide support here to get people onto freedom tech, please respect the limits.

Jabber ID is for XMPP. You're saying you can't join the XMPP or Signal?
For Signal, if you copy paste the link in the app, or just go to it in a web browser, it should work.
I am aware that Jabber is XMPP, just telling you what I am seeing when I select your Signal link. I cannot copy the link inPrimall.
The same link is at the bottom of our website, if it's easier to copy it from a web browser. https://simplifiedprivacy.com/
Used XMPP link from your site, also didn't work.

When I try OMEMO fingerprint link I get 404 not found.
Try messaging me 1-on-1:

Then I can invite you to the group
Group:
The group has no keys, it's an open public room. You add them differently as "Join Group":
