dropdown issue on Microsoft Edge Browser

Hello,
I recently purchased JUX Mega Menu. The module is properly installed and configured in Joomla 3+ environment and works great on every browser except Microsoft Edge. When I visit my website from Microsoft Surface device (tablet - touch mode), dropdown menu does not appear in Edge browser as it does on other browsers. I must keep pressed with my finger the parent item until the dropdown menu appears which is really inconvenient. Is there any patch or update for this issue?
Thanks in advance.
