Define the RedirectURI for VNext Web with OAuth

Hi all,

We have had an issue for a while with Vnext Web and OAuth using Entra ID, and that is when we log in, Microsoft redirects the user to: PAGEURL/vnext#code=231313123
Whereas it should redirect to: PAGEURL/vnext/#code=2313213213.

I am struggling to figure out exactly where Vnext web gets this redirect URI from, as it does not seem to get it from our OAuth authentication configuration at all.
Setting the RedirectURI registry key does not seem to change anything for the web version.
Really I just need to ensure that it ends with a trailing forward slash.

Best regards
