IPhone notifications not showing on Macbook Pro

Since yesterday, the notifications I receive on my IPhone don't show anymore on my Macbook, and this despite having "Allow notifications from IPhone" on my Mac, though it doesn't show me which app I can allow notifications, which could be shown previously).

(don't mind the fact that my Macbook is in french)

Can anyone help me fix this so I can get IPhone notifications back on my Mac (PLEASE)?
