Hey Neil,
I have not experienced that issue myself as of late on my test environment. Can you please temporarily revert back to the default WP theme and deactivate all plugins other than ours to see if the correct dates display in the related events?
I also took a look at our reports to see if any bugs have been identified regarding related events displaying the incorrect dates, but wasn’t able to find anything. Do you notice any sort of pattern going on? And can you elaborate on this statement:
They’re not recurring events but they are similar in nature.
Thank you and I look forward to your response. Enjoy the rest of your Wednesday!
