SharePoint App on iOS - Additional credentials error

We are seeing this same error as well after upgrading to iOS 13, or iPad OS.

We also get the blank screen the first time in, go back out, then it shows after clicking the link again.  The page is rendering the same as a PC browser because there is extra information at the top making even less usable real estate on the screen of an iPad.

The page navigation also is messed up because after clicking on links within the pages, instead of the "upper left" back arrow stepping you back out with the same "breadcrumb" path it just plops you back at the SharePoint iOS "find" screen.

The error seems to only happen on pages with Document Libraries, which for us, is pretty much every page.

Please help fix this Microsoft as it has become very inconvenient.

Thanks
