This is a common problem when switching from one device to another really quickly. Before you move from one device to another, you need to make sure the game saves. This can be done by toggling checkboxes in the options menu, waiting a few minutes or completing a match (the safest method).
The good news is that CS is able to track the purchase and give you back the HP/CP that you lost.
That “common problem” is the same issue as the legendary token exploit which you has fixed…
Why is an exploit which gives you an advantage not fixed?
Btw: I had this issue months ago. But it was a stark salary for 99€!
And it took me more than 6 weeks to get my 20k HP!
Of course I didn’t get any compensation or even an excuse.
Well that explains my HP disappearance on my iPhone switching over to iPad. Thankfully I sent out a message and hopefully getting the hp back! Thanks for the info! Won’t be switching so fast next time I make a purchase!
