I don’t know that I’d go so far as to call this a bug because it doesn’t have any detrimental impact (at least not now, it may have for me just after the upgrade), but it does seem to be a glitch.
One of the issues that I noticed with the upgrade is that my streak vanished. I had played a few questions the day before my time, then when I first logged in after the upgrade, poof, my streak was gone in a puff of vapour. I was not at all pleased at the time but have since resigned myself to “stuff it, it’s only a streak”.
I did some more questions so I returned to a streak of 1 day. However at the end of the day I got a practice reminder, which I have set for 7pm my time. I didn’t do any further practice that day to see whether my streak reset the next morning my time again; it didn’t.
I’ve had the reminder turn up every evening since despite the fact that I’ve done some practice each day. It’s just turned up again now notwithstanding that the streak counter on the dashboard shows a green tick indicating that I’ve done some questions that day.
I just took a look at my settings. My timezone APPEARS to have been set to American Samoa (GMT-11), but it probably isn’t really. My real time zone is GMT+10, the reminder is set for 7pm, and the reminder e-mail is coming out at 7pm my time.
I was going to set my timezone correctly and toggle the reminder on and off BUT the page will not allow you to change only your timezone; it demands a password change as well because otherwise you get an error about the password being blank. And I would rather NOT change my password.
Just to add to that if I click on the “Set a reminder” link on the dashboard it says “No reminder set”, notwithstanding that it appears set on the account page. And obviously… it IS set or I wouldn’t be getting the e-mails.
