I logged a support ticket through the support site but was informed that "For bug reports for the mobile app, we are currently accepting them via the Mobile Bug Report forums at http://us.battle.net/wow/en/forum/2690193/ "
It has been about a week and I can not log into the Guild Chat function on WoW Remote for my characters on Moon Guard in the guild called Impulsive. I can however log into guild chat on WoW Remote using other characters on other realms. I think that this may have to do with the fact that the guild recently changed its name from Ashen Vanguard to Impulsive. This may have caused a bug which prevents me logging into guild chat on characters in this guild. Any help with the matter would be greatly appreciated. I was waiting for any data update to resolve the issue but it has been about a week so I thought that I would post here to get the problem resolved.
