Hey @cazzzp, thanks for reaching out to us.
I moved your post out from this thread, as it dated back to 2017.
I'd be happy to look into this with you, I'll just need a bit more information.
For example, are you having trouble with the formal of your Microsoft Word documents when you preview them via the website, the mobile app, or the desktop app?
Do you find that this happens to specific files?
Give me a shout whenever you have the chance to check this out, cheers!
