Notification test makes Andriod phone sound twice

[Essam Daoud]

When I place a limit order, my mobile phone makes the tone twice but I expected it once. Changing the town on the phone does not have any effect (tone change expected).

Turning the phone of and on did not fix it. Any idea how to fix this?

My MT4 terminal has the following checked.

Enable Push Notifications, and Notify of Trade Transactions.

It was working OK before but I don't remember what I did that might have caused it to sound twice and even ignore the tone change in the phone app settings.

Thanks
