I have two basic accounts, one for business and one for personal work. I want to switch the business one to a a premium account and not affect the personal one. I followed the instructions on “merging” (not a good name, by the way, the accounts aren’t really merged, just available under the same login, buit clearly appear to be separate), and am happy with the setup. I just don’t want to end up accidentally buying two premium accounts when I only need one. I suspect the answer is yes, that works, but I want to be sure before proceeding.
