For a while now I’ve been receiving my e-mails in Spanish instead of English.
Support Game Master Arlyeton already did all they could and said to post on the Forums.
They’ve already tried changing language internally, resetting my password to reset the cache and other troubleshoots.
Blizzard please fix, I just want to be able to read my e-mails.
Update 07/2020:
Got another e-mail, still in Spanish.
