Hey guy's , i tried to send a test amount of 1 PLU from exchange to myetherwallet.. that was 8 hours ago.. still it is not showing up in MEW under PLU..

Does anyone know how long it should take to transfer & show up ?

If it should of transferred sooner , what steps can i take to see why it did not get transferred ?

P.s. i had also transferred ETH to the same wallet address last night it worked
