Hey @Mikael,
I’m sorry to hear about these issues! I have a few specific questions here that should help reveal the nature of these issues:
1. Do you have this problem with several other events? Or is the event you shared the only event with this problem?
2. Is the event you shared limited by age, at all? Is it an “adult” event on Facebook, so that perhaps you have to be 18 or older to fully view and explore the event and confirm attendance to it and such?
3. Can you share your “System Information” with us? Here’s how to do that → https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Thank you!
George
