How to merge two domains/products for a same email address

Thomas LUK

Hi everyone, I don't know why there are two domains for the same email address. (see attached image)

These two accounts or should I say products are completely isolated. My question is why does this happen and how can I merge them back into one?

Thanks

Looks like you set up two different domains, maybe signed up twice? You could delete one and focus on the other. But there is no way I know that you can merge the two together (except manually).
