The uploaded documents are not shown on page reload for document library web part

[s-KaiNet]

We observe a very strange behavior with all of document library web parts on all tenants where we tested.

Problem Definition

Newly added document disappears after page refresh. If you refresh second time the file appears.

Steps to Reproduce

1. We have a document library web part with modern experiences.
2. A user uploads a document - the document is immediately visible in the UI.
3. The user reloads a page
4. The uploaded document disappears.

You can use drag-n-drop upload, or upload button, it doesn't matter. Sometimes you need a few refreshes until file appears in the UI. It doesn't matter how many time you wait after the initial upload - for example you can upload a file, wait 5 minutes, then refresh - the file will disappear, then refresh again - it will appear.

This is the video demonstrating the problem:

Hello @s-KaiNet,
Thank you for bringing this issue to our attention. We will look into it and get back to you shortly.

Hi @s-KaiNet I was able to successfully reproduce this issue in my tenant following the steps described.

The behavior matches exactly:

1. Newly uploaded documents appear immediately after upload
2. After a page refresh, the document disappears
3. A subsequent refresh brings the document back

I’ll raise a bug with the engineering team for further investigation and resolution. I’ll update this thread once I have more information from them.
