Anyone having issues purchasing the 7000 gem pack?

Ever since Weapon Master has been available as the bonus card in the 7000 gem pack, I'm unable to purchase it.

I can click on any other gem amount and it works fine...but clicking on the 7000 gem pack does nothing! It just clicks and nothing happens.

I am using LG G3. I even did a factory reset on my phone and issue still exists!

C'Mon man...
