Strange never asks me for a password change?? version 1.2.10 and yes they are effing slow on updating the APP, they must think everyone owns a macbook pro or something.....
I know on latest firmwares, one cannot simply, as in the past, ignore setting a password when first entering the config (winbox).
Thus I suspect that thinking has filtered over to the IOS app but like most things on the APP, not complete or up to date.
