When my organization use Safari to access Sharepoint Online, we got this authentication error on top of the page, at each sidepage we load.
The error message extends with one more message per click sometimes and can after a while take up the whole page.

The pages seems to work fine in Edge browser, but the most of our user base use Safari, and we need it to work flawless there.

Translation of error message from Swedish (in image below) to English:

“To be able to view this information on this page you have to verify your identity. Click here to add additional authenticationinformation.”

I can’t even add the picture from my iPhone to this forum. Since the picture on my phone are in format: *.jpeg and not *.jpg, I just got this error message that image can’t be uploaded here to this forum.
