I know some players have been having an issue with this, and some of it is indeed tech related.
Some players, however, continue to have UI related issues. If you haven't already tried a full reset UI and tested this without ANY addons, I'd recommend at least testing it.
If you have and that doesn't seem to help, it probably is connectivity/tech related.
