Microsoft Defender like all other Microsoft products is broken and simply doesn’t work.
When I load the page I get some Javascript error showing:-
And then when I try to whitelist IP addresses in the Threat Policy > Tenant Allow / Block List – it is impossible to add anything; it just keeps telling me “Specify up to 20 valid IP addresses.” – I just did that but still it doesn’t work.
Guaranteeed that there will no support; and yes this is typical of Microsoft.
