No reverse alias for Free plan?

I don't think I understand. THe free plan allows

10 aliases
1 mailbox

But now I can't create any reverse alias at all

Works fine for me on free, but I created an account separately and later logged in with proton, IIRC. Might be related to the timing, as they were in transition between being owned by proton then.
Where's the problem? SimpleLogin Premium is required to initiate a new email conversation with an alias.
