MaterialUI snackbar doesn't get popup at first render.

Let suppose there is a landing page and on landing page there are 2 options one is for Login and another is for SignUp.
On Login page I am just checking whether cookies are enable or not, so if cookies are blocked then I want to show the snackbar, same goes with SignUp page.
Now what happens is when I clicked on the Login button, the Login page opens up but if the cookies are blocked then snackbar dosen't pops up, but if I refresh the Login page then snackbar pops up.
I want to popup snackbar at the first render itself.
If I use 'a' tag then it works fine but using Link tag it dosen't work.
Can someone please guide me on this.
