So I translated my book's German page to see how it was set up and noticed they have tags! The UK pages don't have tags so obviously I was excited. I tagged my book with a mix of English and German tags. Then I signed out and signed into my husband's account to vote on the tag and lo and behold the tags were gone. So I tried to tag it under my husband's name hoping they'd stick. Nope. The tags are gone again. The German Amazon site is weird. Thought you ought to know.
