Tucker_P_Ezoic Okay. I think I've got it solved. Though I would still like to give a specific point of insertion, such as always load below the first paragraph. Your caching comment and noticing there are duplicate setting in Humix led me to at least some consistency.
1) There are 2 points to set the Viewport in the Humix dashboard. Firstly, under the Auto Insert tab. Secondly, under the Monetization tab > Universal Floating Video Player > Advanced Settings. I had previously had 2 different settings in these two locations, leading me to believe that may have been at least part of the issue. Now they are the same.
2) After making sure my Viewport settings matched, I cleared the Auto Insert Cache under the Auto Insert tab.
3) I then cleared the cache on my browsers, closed the browsers, and re-opened them. Now all test points are showing the video in the 3-4 Viewports position, which seems to bounce around a bit putting the video after the 1st, 2nd, or 3rd paragraph varyingly. But that it much more desirable than over the featured image above the title.
Thanks for your assistance on this and leading me to an answer. I appreciate your patience and help.
Cheers!
Ken
