Thanks for the reply Andras!
Yes, WordPress is using “New York” as the timezone (see first screenshot attached)
The timezone settings inside the plugin actually do not appear to “stick” whenever I try to set them. There used to be a button on the page, which I don’t recall exactly what it said but I believe was a prompt to apply the sitewide settings to all existing events. Now I have a dropdown and a checkbox for “Timezone mode” and “show timezone” and any time I try to change these values, they default back to “use local timezones” and a status of “unchecked”. (see second screenshot)
And to confirm, I’m using the most recent version of both plugins (see third screenshot)
Happy to provide any additional information as needed. Thanks for looking into it!
