Hi Muhammad, happy Saturday! 😎
Thanks for reaching out. It seems we’ve identified a bug here, and I’ve escalated this to our engineering team. We’ll keep you updated as soon as we have more information.
In the meantime, I recommend opening the Apollo column and saving it individually. This should allow you to save the configuration without any issues.
Thank you for bringing this to our attention, and let me know if there’s anything else I can help with! 😊
