You can't activate referrals anymore, all just says waiting for them to subscribe

This applies too all, including ones that were ready to be activated.

I am not sure if new referrals are possible but considering that I got 2 today with existing links I shared it seems yes, also not sure if the invited can activate it, or only applies to the invitee.

If you have any unused rewards then check your go as it would be useful to know if they can still be used, and if not then bug or policy.
