OK, that makes sense and explains the “installed 15 days ago” thing. I uninstalled it. Thanks for explaining that.
But to shift the topic slightly, and this is more for your benefit - the old Welcome App must have, when nothing was inputted into the HTML code area, had no effect on a rendered page. That must have been my case, I must have enabled the Welcome app and entered nothing in (that was what I saw when I looked at it before I uninstalled it), and of course there was no effect on my pages.
But the new Welcome App seems to influence a rendering of a perhaps 20px blank/black space at the top of a page even when nothing is entered into the Welcome code. That’s why I noticed it.
Should that be the behavior? I certainly wouldn’t like that. I mean, the Welcome App would be nice to put in temporary messages, but during normal times not have anything - but I’d hate to uninstall the App just to not have anything - as it is now, as I mentioned, when no code is entered, it still influences what the pages look like.
Or am I missing something?
