Hi Michael-
I checked out the website you sent over privately, and I noticed that the issue occurs when you begin to scroll down the page on mobile.
The page content seems to leap abruptly up as soon as you start to scroll a little bit down the page. This isn’t how the Pavilion theme normally operates, so I suspect that it might be related to one of your plugins.
I noticed two that stand out as possibilities- Sticky Menu or Anything Scroll and Sticky Menu on Scroll. It’s possible that these two plugins are conflicting with each other since they’re trying to accomplish the same task- try disabling one or the other and then check to see if the behavior persists.
