I noticed my email notifications for this forum were going to an obsolete address, so clicked into my profile to change it.
On changing the email (first time), I was sent a validation email to the correct new address. I validated. Logged out. Logged back in and noticed the email setting was still my old address.
Changed it again. This time it appeared to change without a new verification. Yet on refreshing the old address returns.
Tried one more time and added a phone number hoping the additional data would trigger a proper save. The phone number was added, but the email reverted to the obsolete one.
I suspect this is simply a bug, but perhaps someone has more info?
