Loop synchronization error

Question

Loop synchronization error

Vrablik, Karel 0

I am having trouble synchronizing Loop pages on my company network. The error message is
User's image

After several attempts at synchronization, I get an error message
User's image

What could be causing this?

I tried a different browser. Network without VPN. Clear browser history. The problem also occurs on mobile devices.

How can I fix it?

Hello @Vrablik, Karel

Welcome to the Microsoft Q&A Community!

Thank you for reaching out regarding the synchronization errors you’re experiencing in Microsoft Loop. To make sure we're aligned and avoid from any misunderstanding, please let me know a few details about your issue by answering these questions:

As you used the tag "for Business", may I have your reconfirmation if you are signed in with a personal account (e.g., @hotmail.com, @outlook.com), an education account (e.g., @school.edu), or a work account (e.g., @yourcompany.com)?
Are you accessing Loop via the web app, desktop app, or mobile app?
If you're using Loop web, have you tried opening it in Incognito mode? Does it work there?
Is this happening for all users in your organization or just your account?
Are you able to create new Loop pages successfully?
Where are you creating Loop pages?

Your responses will help to identify the issue and I can provide the most appropriate solution.

Thank you for your cooperation, and I look forward to your reply.

Hello @Vrablik, Karel

Thank you for the detailed information you have provided. Based on your description, the issue appears to be isolated to one Loop page within your workspace while other pages created from the same template function correctly. To confirm whether the problem is limited to that page’s content or components, please try creating a new Loop page in the same workspace where the issue occurs. Use the same template you used for the problematic page, if applicable.

Then, add representative content to the new page. Please include the following, in the order listed, and pause five to ten seconds between each action to allow synchronization to occur.

Plain text paragraphs of at least two to three sentences.

A checklist or task list with 3 to 4 items.

A table with three columns and three rows and a few numeric values

One Loop component you commonly use on the problematic page, such as a task board or a voting table.

One external element, for example a pasted link or an embedded file smaller than five megabytes.

Next, confirm whether changes propagate across devices. Open the same test page in a second browser profile or device and verify that updates appear within thirty seconds.

If the new test page exhibits the same synchronization errors, the problem is likely broader than a single page and may be related to data protection controls, tenant configuration, or a service-side issue. In this case, an administrator should submit a support request to Microsoft and ask for investigation by the Microsoft Data Protection team.

For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.   

To streamline the escalation, please prepare and include the details below.

Tenant and environment information

Reproducible steps and scope

Screenshots of the error banners and dialogs showing the full message text.

Browser name and version, operating system and version, and mobile app version if applicable.

Let me know how it goes or if you need further clarifications, I am happy to help!

Hi @Phoebe-N ,Today I created a new page in the same workspace. Synchronization is in progress, but page loading is very slow. Several times, the browser asks me if I want to close the page or wait. The same problem occurs with other pages in this workspace. I suspect there is too much information in one workspace.
