- 1st issue I was able to reproduce - user sees this until be scrolls down the page - not a big deal - however, I do recall 100% in my previous tests last month this was not reproducing --> we worked on a fix reported by another user which was involving Gravity forms, so it's a small chance they might have something in recent update..
Last time I tested they had : 2.8.1
This time: 2.9.4 latest gravity forms verison up to this date

- Additionally, the counter for Admin Notices doesn’t correctly register notices when loaded on any of the Gravity Forms pages in WP Admin – it says “No admin notices” even though there are several admin notices counted in the counter on any other page in WP Admin UI.
