Occasionally, when trying to open a file or document library in one of our SharePoint sites, instead of opening the file/folder, SharePoint prompts the user to download a file named "preload" (Speicific message - "Do you want to download "preload"?"). If the file is downloaded, then the downloaded file is empty; it has no file extension, is 0 KB large, and opening it in NotePad opens a blank window. This issue does not lock users out of files or folders - when attempting to open the file or folder again, then the user is able to open the file/folder without issue.Currently this issue has only been observed on Apple devices and only while using Safari. Efforts to recreate problem on Windows/Firefox and iOS/Safari/Different SP site have been fruitless.Could this be an issue with the specific SharePoint site or a general Apple-wide problem with SharePoint Online?

My enable content blocker option was already checked when I went to check the box from my Sharepoint site. I receive the 0K preload file every time I select to open something from Sharepoint, any other ideas I can try?
Buen día buen día, espero que estén todos bien.
Cuentan con alguna novedad sobre este tema?

Dear Kaspars Pudans,
Thank you for posting back and sharing with me the detailed information.
I understand this issue only happens when using Safari browser on Apple devices.
On one hand, I recommend you use Chrome to access SharePoint site and open files.
On the other hand, consider that your colleagues experience same issue too, it could be a tenant wide issue, I'm afraid general troubleshooting cannot fix it. It needs to be investigated and fixed by checking your SharePoint site from back end.
So I sincerely recommend that your Microsoft 365 admin, can follow the steps in this article and create a support ticket to contact Microsoft online support. The support team there has more permission than us, they can help you collect logs and involve more resources to investigate the issue from the backend. This would be the most efficient way to handle this case for you.
Note: To create a support ticket, you need to have Microsoft 365 admin privileges.

Your understanding and patience will be greatly appreciated. Have a great day!!

Dear Tina,
I just clarified with one of my colleagues, that the issue only appears on Apple devices when using Safari. Issue could not be replicated on an Apple device when using Google Chrome.
