Sorry for the delay in getting back to you. After I saw your message yesterday, I reached out to our developers right away.
Regarding the issue “Sony Bravia only has channel up and down”:
This is because our current IR code library only supports these two functions for Sony Bravia TVs. We apologize for the inconvenience, but please rest assured that we will continue to improve and expand the IR code library.
Regarding the issue with custom IR codes not working:
We have specific format requirements for IR codes. We recommend that you refer to the following knowledge base article to re-add your custom codes:

We look forward to hearing that you successfully got your custom codes working!
