The activation email being sent out is confusing.
The BIGGEST link Registration on my.fishbank.io isn't actually a CTA to activate your account, it just takes you to fishbank and asks you to log in. I believe this is confusing a 5/7 of the people that signed up under me still aren't activated. It actually took me about 24 hours before I realised I also wasn't activated.
That link should be changed to be the activation link too.
