hmm. Sorry, not sure why.
I have looked at 1.9.8 and a.9.5 - I see it there. Are you logged in as full admin? Admin has to add this block, and then others would be able to use it.
Update: I take it back. I have added it as an admin, but support user cannot see it there, and can see it only on the regular moodle homepage.
hmmm, can your support user navigate to a homepage instead, from myMoodle, by erasing /my in the URL? Or do you force people to go there?
