I have moved your post into your own discussion. Please feel free to create a discusion of your own with an issue or question you may have.
If you haven't already done so, please try un-installing and re-installing the app.
Regarding visiting friends, if you are unable for visit certain a kingdom there may have been an issue with that particular account. The user of the account will need to contact us for assistance. The kingdoms that you can now re-visit may of had their issue resolved.
If you read my post, I did try reinstalling the game and it did not help. In fact, a couple of people have posted the same - reinstalling does not help the element of the day issue.
As for the "Friends" issue, I did post that quite a while ago. Some of the "Friends" I cannot visit are active users, and some are not. For active users, an update should have corrected the issue. There are plenty of "Friends" I can visit that are not active users. In any event, there is no way to contact those people (whoever they are) so the only way to get a fix would then be to list them here and have you contact them. Would you like me to do that?
