I just installed the plugin and have a limited set of options in the Events admin menu (Tags, Settings, Help, Troubleshooting and Event Add-ons). I was eventually able to find a link to Create an Event through an onboarding screen which returned a ‘You need a higher level of permissions.’ message. However my user is an administrator role and I have access to everything else in the admin. I’m removed all other plugins and set the theme to Twenty Twenty. Latest WordPress version, hosted on WPEngine. Resaved permalinks several times.
