MS Forms - image stuck in load

We have the same issue with all our Microsfoft Forms (Quizes). Images do not load, or dissappear on refresh. It affects all forms regardless of the format and size of the image inserted into a form question. You can "stimulate" the images to reappear by opening the collaborative link of the form, refreshing and opening the "share" link again. But they dissapear again in a few minutes.

I am not sharing the grey placeholder box when images do not appear, but I can share the errors I see in Web Development tools when images do not load.:
There is a 404 Not found errors when images are retrieved from https://lists.office.com

GET

When you try to load the image from pointer link above in a new tab the error is different:

{"error":{"code":"NotFound","message":"No user mapping found for user 123456-c769-40ba-84e4-03087c44f5db","innerError":{"code":"UserMappingNotFound","params":["123456-c769-40ba-84e4-03087c44f5db"]}}}

Does anyone has a resolution to this, or a workaround please? It is impacting our educational process and it is very difficult to sort / predict behaviour.

Thank you,

Sandi
