Hi @bchen-hs-eng. I'm unable to repro this. Does this also happen after clearing the WEF cache?

Hi @Adrian-MSFT Thanks for taking a look at this issue. Clearing the cache restored some of the add-in icons but not all.

We have end users of our add-in reporting this as well, and this occurred after we updated our add-in icons in the manifest. Since this did not happen to all our users, we can assume the icon asset urls are correctly set in the manifest.

Is there a way to clear asset cache automatically when the add-in manifest is updated?

@Adrian-MSFT we are having a similar issue with our manifest and are unsure what to do - it's preventing us from submitting to Microsoft for the add-in store. The issue is in some places it shows the icon, and in others it doesn't even try on desktop:

If I manually upload the add-in for use in Excel Online, it does work during testing:

Thanks for reporting this issue regarding the default icon showing. It is on our backlog. We unfortunately have no timelines to share at this point

@jrgilman
Can you confirm that the icons in the manifest are supported file formats? https://learn.microsoft.com/en-us/javascript/api/manifest/image?view=common-js-preview

If they are supported extensions, it will be triaged under the same backlog item mentioned above.
