All members have the same email address!
If, when accessing your members inside the Members section, you find that it appears that everyone has the same password, this is usually because you are using a password manager like LastPass which is automatically filling in your email address as the page is displayed.
The emails on file are correct - unless you press SAVE!
To see your members' email addresses you need to turn off your password manager or disable it for this specific URL: https://app.productdyno.com/admin/members/channel/nnn
where nnn is your customer number within ProductDyno
