Cannot receive reward for field-research
Today I am on the last day of the field-research quests.
I have already collected about 8 stamps today but I still cannot receive the reward: nothing happens if I click on the big orange button.
If I close the window it jumps back to "You need 1 more stamp to receive ....". I already tried to disable / enable WiFi and to restart the game multiple times, with no effect.
Anyone got an idea what could I do ?
