I've tried clearing the cache and I also created a brand new reactive application so my browser shouldn't have a cache at all. The same behavior occurred.
We are on Version 11.9.1 (Build 20359)
Yes I agree it's quite odd, but everything renders perfectly and works as expected after a refresh. I inspected the page in dev tools prior to and after the refresh and I can clearly see the ECT_Provider Div is not present prior to the refresh occurring.
