How do I get dropbox login working through a Universal Window Platform App?

Jun X.

Hi there, I was wondering if someone could help me with getting drop box login to work through my Universal Window Platform App. I have followed the steps through the following guide :  https://microsoftedge.github.io/WebAppsDocs/en-US/win10/CreateHWA.htm , where it turns my website into a window store app but I can't seem to get dropbox working. When I try click on the icon which allows users to login, it crashes the app. On the website it works perfectly. 

Any suggestions would be helpful. I have tried adding https://www.dropbox.com to the URI but it didn't work.  I checked through the console and got the following problem. Dropbox:
APPHOST9624: The app can’t use script to load [website url] url because the url launches another app. Only direct user interaction can launch another app. I never encountered this problem through the website.

I also encountered another error which I'm not sure. is the source of the the problem which was : APPHOST9603: Can’t load the ActiveX plug-in that has the class ID '[Class id here]'. Apps can't load ActiveX controls.

Any help would be appreciated.

Thanks

Unfortunately this sounds more like more of an issue with the Universal Windows Platform, or a browser-level issue, so I'm afraid we probably can't be of much help here.
