Small question (Patreon)

So I just switched that Soraka x Lamb post over from $5+ patrons only to visible to all patrons. Can somebody let me know if Patron sent them a notification/email about the post becoming available? I'm not sure if I have to check "Notify patrons about this change" to let the Polls tier know that the post is now available or not. 

And if Patreon DIDN'T send out any notifications... the post is now available to all my patrons
