Must be related to a connection issue where the click/tap doesn't register.
That's strange because it's the first time someone reports that issue.
I also checked the error logs, and I couldn't find anything related. They have been pretty blank since we cleaned out all the bugs with the v2.0 update.
If you encounter that issue again, please copy paste the content of your browser's console (on most browsers it's done with the right click, inspect page, there's an console/error tab)
Try to log out, clear your browser's cache, log back in.
