We don't have a way to merge accounts or move invitations between accounts unfortunately. We recommend choosing one as your primary account and using that one exclusively moving forward.
You do have the option to change your account email
in your account settings so that is another option. One thing to note is that an email address can only be linked to one account at a time so we would need to delete the older account for you if you wanted to reuse an email address.
If you're unsure of the best way to arrange your accounts, you can always contact us and we'll help you figure it out.
