Desktop Notification / Email not working in SuiteCRM7.9.4

I have been trying so hard and so spending too much time to setup desktop notification and emails for composing but failed all the time in version 7.9.4, it is confirm that these modules are not working at all, simply because these modules are working and function in version 7.8.5, if these problems cannot be resolved, it is really a bad thing to SuiteCRM 7.9.4 simply because it is no a fully functional CRM program.

Is there anyone here successfully to get these modules work in version 7.9.4? Please share how you do it , very much appreciated.
