I just tried to export some avax from X to C, I exported succesfully but now I cannot import it. If I go to advance tab and click import C it just say import succesfully! But nothing happens, no import.
It is a global issue, DEVs are aware about API slowness with crosschain and balance.
However, funds are safe and will displayed correctly as soon as everything will be back to normal.
I will come back on forum to inform you
