I accepted a guild invitation but I am still guildless?

Hello,

Today I applied for some guilds and one of them did send me an invitation. I am pretty sure I accepted it, and it even prompted a confirmation “You can only join one guild, so all other invitations will be removed” etc. But turns out I am still guildless (and the other guild applications I made were indeed removed). What happened?

Thanks!

Edit: I tried reapplying, and it simply won’t go ._. I am unable to reapply
