I logged in with my bsky account, created a new repository, added my ssh key in settings. When trying to push I got the error git: git@tangled.org: Permission denied (publickey).
I'm assuming my ssh key wasn't synced to the knot? I did make sure the correct ssh key was offered using ssh -v git@tangled.org.
I waited about 15 minutes to make sure the key sync wasn't just delayed a bit.
I then created a tngl.sh account and repeated the same steps, resulting in a successful push.
