rerouting and redirect page issue

Hi Devs I have an issue in my react application . I am using react redux and java as a tech stack in my application . It’s an issue of reload and rerouting the page. Also I have tried solutions from copilot but didn’t work that as well. So the issue is -> I am logging in to the application with the saml login , it works perfectly fine and apis are success we are getting response , its hitting out main index.html file and calling our new bundle file main.987.js and ui is getting loaded . Now when I try to reload the same page , it’s not hitting our new bundle file and calling an old bundle file main.453.js and apis are failing and page is not getting reloaded . I tried with the browser history solution also like maintaining the history and all and also tried to write the rewrite rules but that also didn’t work . It’s a hot and assigned to me . Backend team is saying it’s a ui issue but I am suspecting a backend change . Anyone face the same issue or know any solution ,I would really appreciate. Also,we are not using express js using react router only
