German auto correction in Studio 2015 still not working properly

I installed Studio 2015 SR3 only recently and found that the problem described in the thread below still persists. According to Paul Filkin, the issue was scheduled to be fixed some 2 years ago. Any news on this issue?

Regards,

Andrés
