Troubleshooting didn't work. Multiple King games are affected on multiple devices, I think an update is needed..
Is it possible to sync with the kingdom and to facebook again later to see where my friends are?
There's not much to edit there, but everything seems to be ok..switching my email off and back on and changing the visibility to 'friends in stead of 'only me' didn't help.
What happens if I remove the app there? Will I lose my progress?
