After last week's Youtube app update on my LG 55UF6807 I am unable to use the app anymore. The update was applied on 18.11.2017 (Saturday). I have tried reinstalling the app. Since no downgrade functionality is possible then I would like to ask - what can I do to get the app back to a working condition? Other apps work - I can stream Netflix and use the browser etc. Added a screenshot of the view greeting me when opening the app. Casting does not work, the visible page is not usable in any way either.
