Notifications are gone

Getting this issue since yesterday. Notifications were working fine, but suddenly all the notifications disappeared permanently. Notifications page became empty.

A few hours later, the problem appeared again, and yesterday's notifications also disappeared.

The notifications were gone yesterday, then they came back for a while and now they're gone again.

yes not working again plz fix asap

My notifications have been wiped completely and i can't keep track of who i'm responding to.
