Dear @Edward Chong,
Welcome to Microsoft Q&A.
Thank you for sharing the details of your case, and I’m truly sorry that you’ve had to deal with this issue for such a long time.
I’ve reviewed your scenario and researched this behavior based on Microsoft’s official documentation. According to Microsoft, when SharePoint access is restricted for non‑compliant or unmanaged devices using app‑enforced restrictions (via Conditional Access), users are limited to browser-only access. In this mode, background requests to retrieve certain resources such as site assets, thumbnails, or logos may be blocked or inconsistently rendered. This is a limitation of the access control model, rather than a site- or group-level bypass mechanism. Microsoft documentation does not describe any supported configuration that allows selectively bypassing these restrictions for specific sites or logos.
You can refer to this article: IT Admins - SharePoint and OneDrive unmanaged device access controls
Because of this, differences in logo visibility between sites can occur depending on how and where the logo is stored or requested, and whether that request is treated as a protected download under app‑enforced restrictions. This behavior is considered an expected side effect of the security model, not a misconfiguration at the site level.
Regarding escalation, it’s important to note that this forum is a user-to-user community, and moderators here don’t have visibility into, or the ability to escalate, Microsoft Support tickets. To investigate this further or obtain an authoritative confirmation (for example, whether this is a product limitation or a potential service issue), I would recommend that a Global or SharePoint Administrator open a new support ticket from the Microsoft 365 Admin Center and explicitly request review by the SharePoint product team, referencing the behavior under non‑compliant device access controls.
You can raise a new support ticket from Microsoft 365 Admin Center>Support>Help & Support.
Thank you again for your patience throughout this process. I hope the information above helps clarify the situation and sets clearer expectations. If you have any further questions or need help with related topics, please don’t hesitate to reach out.
