Hi @fjfish
There isn’t a way around this unfortunately. We actually operate a one account per email address policy.
Affinity is a tool used by accountants, bookkeepers or those with multiple accounts which allows Affinity users to use one email and password but access multiple accounts.
There’s more information on this here:
