Activated challenge - not loading

Once again!  I activate a challenge and unable to complete the challenge as game not loading.  I activated the challenge for Yahtzee Wild but the game will not load.  Spins round and round and says please wait loading!  Why is Pogo having so many issues?  This is like the third time in a week that I've had issues with Pogo!  I have cleared my cache at least 6 times per day trying to play a game on Pogo!  Beginning to rethink a renewal on my subscription.
