Was there any indication of the order of the words? If there was no indication of what order the 12 words go in, that's pretty much impossible to crack with brute force. Someone may have found them but they're useless without the order (or enough of the order to reduce the brute force keyspace).

No indication but it was just a 3-11 and 4-10 switch so shouldn’t have been too hard. The alternative is that my phone has been hacked. 😲
