Subscriptions not showing up when I open account in browser - only on the AVG app. And need to put all under same email

I have purchased three different AVG products and they are listed in the AVG app on my laptop. They are only listed however; I am not able to manage them at all in the app. I need to manage these accounts but when I click the “Go To Account” button on the app, it opens a browser window. I log in and see that it says I have NO subscriptions.

I also see that I mistakenly opened one of the accounts under one email, and the two others with a different email. I would like to get them all under one email.
