I got the same issue. I use zoom web sdk 1.9.9 When I start sharing screen, the loading box of the Zoom Apps would pop up and show an infinite loading icon. However, if I press on the Zoom Apps icon before sharing screen, the box would load for a little while and show info. After that, whenever I share screen, the loading icon issue would no longer exists. ---
