Unable to Claim Classic Characters?

Hello, does anyone know why I might not be able to link/claim my character from Classic, despite the Battle.net account being linked? As seen below, the Battle.net account is linked to the correct region, but the character table reads “no available data”.

As a bonus, my character is Horde side (and my warcraftlogs account is joined to a Horde side guild) but my personal logs icon still shows Alliance.

Anyone know what’s going on here?

Not supported. There is no API for Classic yet from Blizzard.

Got it, so I can go ahead and ignore all the faction flag stuff for the time being?
