Ironically, this is the second time this has happened to me with the Astra theme.
I’m having the same issue again at https://www.propeakmedia.com.
IMPORTANT: This issue is ONLY affecting the tablet / mobile versions of the site.
This time it started when I added two additional items to the primary menu. I’ve tried disabling plugins, I’ve tried removing the new menu items. No fix. So, navigating through this site is completely broken.
The first time this happened, I was able to fix it myself but it was an accident as I was making a long list of other changes.
