Truth Social is not open for business yet. Maybe you went through a beta testing thing?
I’ve heard that many have downloaded the App and are waiting.
Well, then there's a cautionary tale here. I went to the Truth Social site on my phone (looked legit, used the advertised icon, etc.), downloaded it, signed up, was asked for my credit card (big mistake). They ported me to a company called "TUDUM" (I assume it's "TOO DUMB"), which is a video/media viewing site. I called their hotline and canceled everything. BTW, the "download" never showed up on my phone. This TUDUM site is off-shore. I will now watch my account like a hawk to see if they will scam me. BE CAREFUL!!
