Heya, thanks for making this.
Yeah we're currently missing a way to manage that stuff, but it will continue to renew.
We can throw the Orion+ section on the billing page for members (at least, so long as you have an active sub - making a new one might not be possible for now)
The api credits is a bit more complicated, since your billing is now tied to the family owner and thus any api credits billing would now go through their billing, rather than your standalone.
Ideally this could be managed in both the whole account and individual basis but right now that's just not possible.
If you reach out to support@kagi.com, we can transfer your individual api credits to the family account - but then I must note that it will be usable by any member and not just you.
