Have you tried some basic TROUBLESHOOTING techniques such as:
Have you tried completely leaving that game mine....going to a different game mine & breaking a few tiles....then go back to the valve?
You can try logging out & logging into the game/Facebook/Portal/Google Play, etc.
Make sure you are running the most up-to-date versions of the game, Facebook, Google Play, browser, phone/device/PC operating systems, etc. (Depending on what you are playing through).
Try clearing your cache, cookies, history, etc (if you can do this).
You can also try uninstalling & reinstalling the game, Facebook, Google Play, browser, etc. (But ONLY do this if you have your player ID number & game progress registered with either your email address or Facebook account).
If none of these suggestions assist you.....I suggest that you contact Pixel support directly.
I assume that you know how to contact Pixel support?....if not I can give you the details 👍🙂
Have you checked out the relevant Wiki pages, quests, maps, videos, guides, walkthroughs & hidden gifts.
In certain scenarios it is much more easier to consult, study & follow the maps instead of the videos.
