Mobile menu not working on Dawn 8.0 theme

Hi guys,

I’ve recently upgraded to the newest DAWN theme, 8.0.

I use an app - Buddhaa - for the mega menu. But now that I have done the upgrade, the mega menu is not working on mobile. I have deleted the app, reinstalled it - nothing helps. I checked that the app is enabled under App Embeds, it is. But when I click the burger menu, I just get a grey block. This is ONLY on mobi, desktop is fine.

I really don’t know what is wrong, can anyone help?
