We are using Oauth 2 authentication to get access to user's documents. Once user has logged in from the sign in screen and granted access to his files, Dropbox is not redirecting user to the redirect uri we have provided. User need to refresh the page to get it working. Its happening in Microsoft Edge browser only.
Steps to reproduce the issue:
1. open https://m.hays.co.uk/speculativeCV/ in Microsoft Edge Browser
2. Click on the Dropbox icon from Upload you CV Section.
3. Login with valid credentials.
4. You will observe that a blank page appears with url like
https://www.dropbox.com/1/oauth2/authorize?response_type=code&redirect_uri=https%3A%2F%2Fm.hays.co.uk%2FDropBox%2F&state=%2FspeculativeCV%2F%3Fq%3D%26location%3D%26locationId%3D%26locationSet%3D&client_id=k73f7xt6ngscn7g
5. If you will refresh it the documents will appear as it has redirected the user to the redirect uri successfully on refreshing.
Below is the user-agent of the Edge Browser
