OneDrive first time load on Opera browser takes a long time.

[Tom Lacey-Johnson]

Can anyone tell me why when using OneDrive on Opera browser it will load and show folders but it seems to be loading content in the background by showing the loading wheel in the tab? If you reload it seems fast and responsive.

Well, I think the problem here is that Microsoft does not support Opera in the same way they support accessing Office 365 using Google Chrome or FireFox

That's odd when it's built on Chromium.
