# Q\&A for Preview Versions **Q: Why won't CubeOS find my Zigbee dongles?** A: As we can not include and maintain all the models in our compatibility list, only tested dongles will work with auto-discovery. If your CubeOS won't find it, please configure it manually. **Q: Are Built-in Matter components certified?** A: CubeOS is still in the developer preview stage, and is yet to obtain certification. **Q: Why do issues remain unfixed in new versions?** A: Due to the routine of the development team, some versions like V0.2 will focus on new features. Some identified bugs will be fixed in future versions. Additionally, certain bugs may not restore and require more efforts to navigate. **Q: When will CubeOS support xxx platforms?** A: As we don't have infinite developing resources, only popular installation methods are supported and verified. Alternative methods like Proxmax VE may work but are not recommended. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
