I was enjoying this game until I upgraded my phone and lost all my progress. Then the game failed to function on my new Samsung device. Screen freezes after coloring 5-6 spaces, the only option is to exit, close, & restart only to have it happen again. I contacted support TWICE and was told my issue would be passed on to tech.(I tried uninstall/reinstall, logging in under both google & facebook & playing logged out with no success.)
