Have you tried completely shutting down your game & restarting it..... fully closing down....not just swiping into the background?
Tried clear your cache, cookies, history, etc?
If you have your player ID number & game progress registered with either your email address or Facebook account....try uninstalling & re-installing your game.
If none of these suggestions work for you....then i suggest that you contact Pixel support directly.
You can contact Pixel support directly through your game settings menu
Alternatively you can contact Pixel support directly via this link
