Once configured in the preferences, transparently redirect to your instance

I was about to give 2/5 because I thought this addon no longer worked however, I was redirecting to elk.zone and putting in different instances to redirect too, I realise that it is Elk that seem to have changed something that has killed the addon.
This addon can still redirect any account to elk.zone however, you get /authorize_interaction?uri= when redirecting from posts now.
