Unable to save assigned manager in Azure AD when the sync is enabled

The manager field within Azure AD can be changed, but it fails to save for any user in Azure AD if sync is enabled!

We are using Azure AD along with on-prem AD. Out of 2000 users in AAD, about 150 of them are synced (using AAD Connect). For the sync users while we can change the manager information in Azure AD (such as assigning to a different manager), but unable to save the changes (due to account being synced).
Is there a fix if this is an issue?
Is there a way to have sync enabled for "Identity" fields, but for others such as "Job info" and "Profile info" categories to be changed in Azure AD even when the sync is enabled?
If we are not updating for instance the Manager information from On-Prem to Azure AD, then why we cannot modify it in Azure AD?
Why is the field appeared to be read only?

I have heard that as long as “Identify” fields are untouched, we can modify “Job info” and/or “Profile info” fields in Azure AD. I guess when sync is enabled for a user all fields are greyed out and become Read only!
Can someone to please provide a reason or link to a solution?
I do not have permission to access to on-prem to change the manager in on-prem to be replicated to Azure AD.
In a nutshell, I am using Power Apps to change the attribute of Azure AD without any issues, however for synced users I am unable to save the changes.

    Thats by design yes.

    Manager is a sycned attribute and therefore can only be changed on-prem.

    Hi all
    If there any workaround? We have a hybrid environment and some users are cloud only for a certain reasons.
    So we couldn't set manager for synced user if the manager is cloud only user.
    Sure, we could use custom attributes, but we would leave it for last.
    Any suggestions appreciated.

    I am having the same issue.

    After changing manager in on-prem AD it sync with AZ and changes the manager, but after 4-5 hrs. it changes back to the old manager.

    It only happens to one user.

    Any Idea why it might happen?
