I have all of the protections enabled, did not create a "send" transaction, never received an email, SMS text, and no email for the transaction- nothing!! How is this possible???!!!!!
It's likely someone got a hold of your seed, in which case they could simply import "your" funds (private keys) in their own wallet of choosing, eg electrum, and thus circumvent all the security measures..
How they got that seed- i don't know. perhaps a RAT, keylogger, again, i don't know. Did you have your wallet only on your iPhone, or also on your PC?
