Samsung Galaxy cardback?

Hey, just today I´ve noticed that my Samsung Galaxy cardback from logging to Samsung device is missing. I though it´s bug on my side, but I´ve tried to check my alt account and it´s gone from there too. Restarting game doesn´t work. Is anyone else having this issue? Is it a known bug or should I contact support?

P.S. I know it´s not a big deal, I don´t use it that much, but I hate having my earned cardbacks vanish from my collection for no reason :/

You are right it is missing though I had it

Yeah it has gone missing. Must be a bug

Nevermind, it seems they´ve fixed it, the cardback is back :P
