I don’t know if anybody suffers from this issue too, but sometimes I don’t get the rewards neither from the mini game, neither from the box in Mystic Cabin.
Today morning I won 3 glyph and I was so happy, because they were new for me, but when I checked my storage, they weren’t there.
Reseting the app did nothing.
It’s not the first time it’s happened, but now I’m sure about it.
Update: The second reset solved the problem, my glyphs are back.
