"alert" noticification issue

[Robert Halterman]

The mt4 has an "alert" by right clicking on mt4 for "Trading" then "alert". I used to get alert push notification to my phone Samsung S4, and now the function doesn't work. The red arrow is suppose to appear after clicking on "alert" but it doesn't show anymore. I seen on one of the forums that there are restrictions to using it and it might be shut off. Is there a way to fix this issue? Thank you.
