Steps:
1. Started Weeding quest The Ties That Bind with Person X. We both got the Standard (free) Plan
2. Did all the steps of the (crafting wedding ring, praying to the Twelve rocks) and scheduled the ceremony
3. Missed the Ceremony day
4. Person X changed datacenters
5. Quest The Ties That Bind stuck in my journal still asking me to schedule the ceremony. Cannot abandon it.
6. Discarded the promise wristlet obtained with person X but still cannot abandon quest
7. Spoke to Sanctum Acolyte NPC and selected option "Cancel Ceremony". Could not cancel because NPC said I did not have the promise wristlet with me anymore
8. As I wish to marry a new partner, contacted support team via ticket number 17448220
9. Support team confirmed by quest is still active but that I could start a new one with the new partner if we both obtain new wedding bracelets and if we talk to Claribel when in the same party.
10. New Partner and I both bought individually the Platinum plan. We equipped the bracelets, got into a party, and spoke to Claribel.
11. Claribel gave the quest The Ties That Bind to new partner starting from fresh, but to me, all Claribel says is "I trust your preparations are going smoothly? Excellent! I look forward to attending!"
12. My new Platinum bracelet has the name of my new partner on it, but if I talk to NPC Etoinelle she allows me to still schedule a ceremony, making it clear it is a Standard Plan. Additionally, my partner hasnt done the steps of the Weeding quest so if I schedule a ceremony, I dont think he would be able to participate as the groom.
13. Tested talking to Sanctum Acolyte again and tried again the "Cancel Ceremony" - this time it allows me to but is requests the Platinum bracelet I got with my new partner.

In the end, I can't cancel the quest started for a Standard Wedding with person X. Ended up buying a new Plan as suggested by GM team (and do did my new partner) and now we can't marry each other with the Platinum plan.
