No matter how many gems I earn from dailies completion, milestones, or even compensations for other glitches, I only get 20 gems at a time for each one. I should have around 1000 at least by now, but instead I only have 250.

 I noticed that it did not seem to be going through, but that I was receiving a few, and today I realized from two instances that the number does only increase in increments of 20 for some reason. Why is this happening? And how can I get all  these gems that I earned?
