Some of you may have noticed a new Head Screener, John, now appears. This is an account set up for a team of developers who are looking into some specific issues which require fixing for the team and the community.
They are not screening any images just running diagnostics, the account will be removed once they've got the data they require. You should then see a fix for a few things in the following weeks, in particular, the Top of the Hour bug.
Thought it best to let you know
Thanks and regards
