Why do we need to mention explicit cors in node api for angular 9 apps

Angular9

Hi,
We have a typical issue, the node api with the below cors configuration works with angular 7.x apps

app.use(cors(corsOptions));
app.get('/myapi/', myfunction);

But with angular 9.x it throws the cors issue which gets rectified when we add the below

app.options('*', cors());
app.get('/myapi/', cors(corsOptions), myfunction);

Any suggestion on this would be really helpful.

Thanks

What I have tried:

<pre>
 app.options('*', cors());
 app.get('/myapi/', cors(corsOptions), myfunction);
