Streaming not possible

Mar 14, 2016

I use a mi 6 with 18.20.09 installed.
Since a few months I cannot steam videos or other content to a TV.
Having a look in the settings shows that screen mirroring is turned on, but I can't search for devices.
Also I do not have ha streaming button available in YouTube.
Can anybody give me a hint how to solve this issue.
Thanks in advance
