The new update killed my ability to use the nintendo zone. I have 2 3ds xl. One updated last night. I went to a McDonalds and the non updated one streetpassed and the nintendo zone icon said I was in the zone. The update one said I was and when I had it search it said "Nope no nintendo zone here" even though my other one and my daughters ds both said yes the is a zone here. So I updated my other 3ds xl and as soon as it restarted it could not log into the zone and said there wasn't on available, but my daughters 3ds, which has not updated, said the zone was still there and she could log in.
So how do I fix this and is there anyway to get rid of the update? We live in a very small town and the McDonalds is one of the few places we can streetpass.
HELP!
Thanks
