I know its not right forum but maybe some kind soul could help me out.
One day when starting Youtube app I got the message that I need to update the app and the next one was that the latest version is not compatible with the device anymore. So i intalled older version, menaged  to open it, but now videos doesnt load at all, there are stuck at buffering forever.

I've tried installing couple of even older versions  but it didnt help at all. Same thing happens in Chrome when I try to  watch youtube via the website.
The built in update app says the device is already running on latest software.

Is there a way of using device with Android 6 to work with Youtube ? Some modified version of the app maybe ?

Also does youtube check server side which version of app is trying to  access it, then and allows only latest clients as a form of forcing  people to buy new gear ?

Thanks
