The notification of open and close position doesn't come to my MT5 App in my iphone

Dear experienced traders,

The notification of open and close position doesn't come to my MT5 App in my iphone.

Do you know any reason?

* MetaQuotesID is linked.

* Notification of iphone MT5 App setting is enabled.

* MT4 App in my iphone works very well.

Thank you in advance and best wishes,

Sky
