Using Microsoft 365 Outlook web mail, I try to view email advertisements from office Depot/Office Max, for example.
For a very long time they arrive with the bottom/footer info only, none of the promo product's images or text is displayed above the footer. Clicking the View As Web Page yields the same results.

Using Microsoft Edge displays the entire email as desired, and the web page link works.

I have switched off the 'Block ads and surf the web up to three times faster' but has made no difference. What else can I do to fix this?

Any advice appreciated.
