Hi,
With the update of 2020.10.3 community edition the dropdown submenu closes after 3 seconds. It was working correctly in earlier version.
Please fix this asap
Could you give us an example of the drop down and let us know whether this happens to a new or an old project?
Also, what is the version of your UIAutomation package?
It might have something to do with this new feature:
But it shouldn’t typically affect previously made projects.
