Hi weegingerbean,
To access SharePoint site collection (note: the public-facing website and the team site belong to a site collection in Small businesses for Office 365) in Office 365 via mobile devices, there is a good workaround to add “?mobile=1” at the end the URL on mobile devices. Please try to change “?mobile=0” to “?mobile=1” to see if any progresses.
You can see this description on the site settings page under Site Information.
Thanks,
Maggie Li
