Hello,
The default registration form (which is next to login form) altered by b2bking doesn't send attachments. If a person selects wholesaler account type, and fills out all info - attaches file. Admin doesn't receive that file (it is non existent)
For more context we also use forminator (atleast planned to before b2bking) and it's forms send attachments as they should, with no issues. (The problem with forminator in this case, is that it doesn't send custom emails depending on the approval conditions)
Also if user creates not good enough password, registration button doesn't do anything (that is understandable, but no notice about wrongfully created password comes up, which confuses the user)
