If you have several stores (more than one) each of them with the loyalty program, you can add them all under one admin email account. They will still be separate but you can easily switch between them.
Separate accounts have the benefit of allowing the marketing team to run different campaigns.
I signed up for loyalty lion on 2 websites through Shopify but I only see members for one on my loyalty lion dashboard. Why?
This could be because you have used two email addresses for the accounts, therefore you have two LoyaltyLion accounts with separate addresses.
To access them simply enter the email address and password you were given on sign up. If you have forgotten your password just click 'reset'.
