Merge Madness continues

I have not been able to collect anything from the trash can for at least 3 days.  The underlying screen has a msg that states Progress cannot be saved.  When I return to the playing screen I usually have sufficient energy to play for a while and it is alwas the same amount.  This all started when there was a weird glitch on the screen when attempting to collect energy fom the trash can.  I can complete levels and collect those rewards.
