yesterday we switched from SMS to sponsored guest authentication in one of our SSID. Everything works great, but a colleague asked me if we could change the email language to German, because some employees don't speak English at all. So I thought I asked you, if you have any idea how to change the language there. Couldn't find anything yet.
we have the same issue here, unfortunately there is no possibility to change the email language. I just gave a feedback about that problem and hope they solve the problem with the next firmware update.
