App does not start

[oski89]

Hi!

I just updated to the latest version (3.7) after getting the issue with "Error: Unable to retrieve access token.".
I followed the installation instructions and successfully installed the app using "Sammy Widgets".
However, when I click the app icon it won't launch. Instead my TV's UI freezes and doesn't respond for about one minute when clicking the remote. Also, it won't let me log out from the "develop" account - I just get an error message saying "Service not available.". Basically everything that invovles "Smart Hub" functions is either extremely slow or just crashes.

I have restored to factory settings several times and tried installing the app again, but the exact same thing keeps happening.

My TV is a Samsung UE55HU7505T (Europe, 2014, H-model).

Any ideas? Could it be that my TV is an EU model?
Let me know if you need more input from me in order to help.

Thanks!
