I have been receiving notifications when a post is accepted as a solution.
I went to the settings to find a way to turn this off as this behavior is very new, started August 1, 2017 but did not find anything.
There is a checkbox next to "Accepted solutions to topics or questions I subscribe to" on the Subscriptions and Notifications page, Notification Settings, under Email notifications. The wording sounds like you check the box if you want the notifications. I have it unchecked.
I also do not "subscribe" to anything in the first place.
Can we please make this more like the other notifications that allow a Never or other digest interval.
