Steinberg won't actively come to this pretracker to collect information. They prefer to collect via messages sent to the following:

• Public or private messages sent to Daniel Spreadbury or his teammates' SNS accounts (Facebook & Twitter) or Email accounts.
• Direct complains filed to the Dorico sub-forum of Steinberg official forum (link).
• Email support or ticketing system provided by Steinberg official or retailers (probably the most inefficient).

If your issue is not related to the Chinese MUI Localization of Dorico, please send it directly to the Steinberg Official Forum.
