A good starting point would perhaps be ‘report-general-bugs’ under the ‘SUPPORT’ section of their Discord Channel.
If that’s not the right place I am sure that someone will just move it to the correct one.
I wouldn’t worry too much about the finer points. The main thing is the content of what you think is still wrong.
Discord isn’t really that much different to the forum here and the more you post the more you will probably enjoy it. Plus you will have direct communication a lot of the time with the developer himself/herself.
