I hope it's not just me, but Primal has been really fucking terrible on desktop as of late whenever I use it.
Everything but my feed has worked whenever I log in, and sometimes just loading my profile crashes my browser tab.
They never gave me my URL and broke the ability to post but I can still view my TL and notifications on there. It does seem to imply that it's always loading even when everything has been loaded on the page though.
I thought the same since I had requested mine to be "RDS" before realizing they just made it my first name.
Trying putting "/herman" after the Primal URL and seeing if that goes to your profile.
