we had a p2 board in the field with 5.4.1 that had 2 sets of wifi credentials. we upgraded the board 5.5.0 over the air and it would no longer come online
i collected the board and examined it: it was fully upgraded to 5.5.0 but it had lost the wifi credentials
it had 2 sets of credentials
i am very certain we did not clear the credentials
we tried to reproduce but have only seen it once while upgrading ota from 5.4.1 to 5.5.0
