Instead of the typical replies and "help" you would get that receives no clarification but rather generic copy paste templates that applies for every thread in this subforum. Let me help you.
Firstly, as per paymium help pages @
https://www.paymium.com/page/helpTo ensure maximum security, Bitcoin transfers are not processed in real time, but are scheduled twice a day from Monday to Friday (lunchtime and around midnight), plus once on Saturdays (around midnight). Once the transfer is executed by Paymium, you will receive your bitcoins in minutes.
Your thread was created 20 hours ago, which I was Friday night in France timezone.
Your Paymium withdrawal should have been processed by now.
Assuming that Paymium withdrawals was broadcasted with a fee of more than 140 sats / byte , your transaction should have been mined in a block and confirmed by now.
Kindly check your Electrum wallet again and see if you have received your funds.
If not, please double check your receiving address from both sides.
If you need further help, kindly provide the transaction id that Paymium gave you after approving the withdrawal.
If you have received the funds, kindly lock this thread.
