email subscribed, but no receive notification

Hi ,

I'm an intel FPGA developer.
Following the guide(https://community.intel.com/t5/help/faqpage/title/subscriptions), I have subscribed to "Intel Community->FPGAs and Programmable Solutions FPGA"

Unfortunately I never received email notification even though my question thread had been replied or updated by others. WHAT's the Problem ?

Before the Intel support web upgrade, email notification works fine , which means I can receive email notification when thread updates. But now it has problem. Please help to tell where to ask help to fix it, coz it's very inconvenient now, coz I have no time to check community thread everyday ?

Thanks a lot
