Hey Nick,
Welcome back! I did a quick check of our logged bug reports and work often with the Eventbrite plugin and am not seeing any tickets nor similar behavior. I see you checked ‘Yes’ to reverting back to the default WP theme and deactivating all plugins other than ours as explained in our Testing for conflicts guide, but can you please confirm this?
When you say it “changes the timing in the Eventbrite page” – can you elaborate on this more? E.g. the start and end date consistently changes 4 hours earlier than the actual start/end time. Also, what do you have set for ‘Leave this event associated with eventbrite.com?‘ (see screenshot below)
Thanks for reaching out and have a great afternoon. Cheers 🙂
