What you were expecting to happen, and what actually happened:
I expected for the Battle rewards to appear immediately after the battle was over. Instead, I had to wait several minutes and perform multiple retries in order for the Battle rewards to appear. Also, the loading screen is stuck when opening the game, with multiple Retries needed to get into it.
How often does this happen? When did it begin happening?
It started since the 29th of September, and it happened almost constantly.
Steps to make it happen again
Win a battle, then wait a little.
