Every time I try to buy a gem pack on facebook, I get this error message:

Any ideas what could this be? It has been like this from a while (around 7 hours)

No idea :)
did you tried another browser . clearing browser cache etc ?

@Haka-Taka yep, both Firefox and Chrome the same. I'll try clearing the cache, but I doubt it would help.
Edit: yep, didn't help.

No idea then .
i am not even sure who you should contact for support .. FB or SP !

Now I can't buy gems even on android

It is related to the account then , maybe you should contact sp

@Haka-Taka I did it right now, I hope it's not account related.

Edit: Tried purchasing in a different app, and it worked perfectly. 😕

Looks like support is sleeping ... no answer at all 🤬

Edit: they told me to contact Google Play Support and said nothing about facebook ........ 😠

Edit: I tried it on my android phone (not emulator), and the purchase was succesful (bought 25 gems to see if it works).

So it seems like it's not account related 😎 (I think it's a facebook related problem)
