iPhone 6s app Puzzles line graph problems

I do the puzzles on my phone. since the update of puzzles, the puzzles I have done are not being uploaded to my rating and not recording it on the line graph. The graph is empty... and I am feeling empty inside. :,(

Sorry if this has been addressed, I briefly scrolled through the forum to find a similar subject with no success.

It's a known issue that should've been resolved two weeks or so with 7.1.6 update, but seems like update was not approved/not send to Apple. Android got an update 19 days ago :(
