This is the guide I used to get the DLC: https://gbatemp.net/threads/dreamlight-valley-rift-in-time-dlc.657448/page-3#post-10548811
I posted this video on my YouTube too, https://youtu.be/jFzVfZK4tBs?is=zAdopf1yorhtbypF
I know the reason too. I think I got banned because I wanted to play online, I switched to Nextendo network with Prelude, in one of the guides, they said to switch it to regular Nintendo servers reboot and then back to nextendo. Im assuming the logs showed my switch having that homebrew, and this was on all on emmunand but my mistake was later also booting into sysnand (airplane mode off) to check something😮💨
[Update]: I’m not banned! Thankfully😆 Users @angelesnja and @rogueify suggested I go into OFW and try to create a new user with my same Nintendo account and it worked😆 so thankful for this community man❤️
