This is probably off topic, but if you don't ask, you don't find out.
I've noticed over the last couple of days that when I sign in to DS on my iPad, I no longer get asked, "Save this password?"
I don't care about that, I always clicked on "Not Now" anyway, but if I leave my iPad for a few minutes, then have to enter my 4 digit code to get back in, I find that I'm no longer logged in to DS, and have to log in again.
In addition, all my history has disappeared, (on my iPad), I may have looked at Expedia, OpenTable, TFL, TripAdvisor, in addition to DS, but leave the iPad for a couple of minutes, then on return, no history.
None of this is a major deal, I just enter a site name on Google, and I can go to the site again, but is there something I've maybe inadvertently done to cause the history to not appear?
I know that I can go on Settings, and click on Clear Searches and Web History, but I haven't done that, and my History searches are still there on my iMac, any ideas?
