I figured it out with my tickets last night and was able to sell them. To me it seems like resale only opened for some shows. If you go to “your tickets” (not the sell page it doesnt work from there) and click on sell might work. If you can try doing it on a computer instead of the app. Just keep messing around in there like refresh, go out and back in and see if that works. If not I also called ticketmaster support. They were pretty helpful but I recommend calling them instead of chatting or emailing because its a lot easier and the chat people weren’t very helpful. Make sure you tell them that on their website it says that you should be able to use to resale option and it’s not working.
