I and others I have asked to try, are unable to use capital letters in our names for Battle Arena. It started the day of or before the last Battle Arena, as one of our members was unable to use the required capital letters in his Battle Arena name.
This is an issue on FB too, for the arena that just ended today as well as the next one I just joined. It automatically changes uppercase letters to lowercase.
We use a naming convention for our Battle Arena names, so everyone changing their name on the day off isn't ideal. Before then would be awesome! Thanks for the update.
It's still not working, it's still changing the uppercase to lowercase. I'm on FB ZS, and I tried from the Kanoplay site too and it doesn't work there either.
It could be that the code for the fix hasn't been pushed to those two platforms yet. I'll double check with the developer who fixed this up.
