Hi !
We need German as indexing language. Actually, we are unable to change from English during the message above:
Temporarily, currently only sysadmin can change indexing language and reindex all documents. Contact Atlassian Support if you need help.
Thanks
Sascha
P.S.: I know that it can only be done by the Atlassian Team, because I am on the free Cloud plan. I would be super thankful.
