This issue is ongoing from what I've read. Check here and you can read about it: https://care.king.com/en/candy-crush-saga/candy-crush-saga-xperia-m4-aqua-compatibility-issues I hope with those troubleshooting tips you can get the app back on your tablet!
To answer the question about getting help, have a little read of this thread: https://care.king.com/en/papa-pear-saga/i-m-not-receiving-my-messages-lives-from-friends For the game not letting you proceed, this happens to us all and there is not much you can do I'm sorry. You will just have to play again.
I don't work for King sorry Cali, I was just trying to be helpful. If you read the post it says that it might not work... I can't really offer anything else.
I'm a little lost B... are you talking about the roadblock or you're waiting for new levels to be released? The gold bars for the roadblock has always been place.
If you are on youtube then always use the 'most recent' filter when you're searching for videos. That way you will more than likely see the latest version of the level. This happens quite a bit so it's something I always do :)
I don't find the promotions any different to the normal levels. I only find a put a little more pressure on myself because it's like a competition, haha. I guess you can always stick with the normal game as the promos don't affect your progression.
Did you log into Kingdom or Facebook? I can only really recommend logging out and back in again to see if that helps. If you were connected to Facebook then maybe the steps here will help: https://www.youtube.com/watch?v=bIYE7aW5jcE
