Can't discover the Smart TV if its name is too long
On a Linux Mint 20.1, trying to connect to an LG Smart TV.
Default device name of the TV was 'PH50SOMETHING' and the device wasn't appearing on the list of Available Video Sinks until I shortened the name to just 'PH' on the Smart TV 'My TV Name' settings.
It then appeared as '[TV][LG]PH' on the sinks list and I could finally connect.
Didn't find any mention of this problem in the README troubleshooter so I thought you would like to know.
Let me know if you need more details.
