Just after topping up PD (100PD at a time) in the daycare, a
notification asking me to top-up PD again would appear in less than
an hours time (usually it appears just around 10 min after I just
topped up the PD). It happened so many times and I have used 2,000
PD just from this asking me to top-up again and again. I have tried
putting in pokemon first then topping-up and topping-up first then
putting pokemon but it still happens. Am I doing it wrong or is
there a bug?
You always pay in advance, so the 100 PD are consumed instantly and
your Pokemon start breeding/gaining EXP for the following 60
minutes. But since the balance instantly drops to 0 because of
this, you receive a notification.
