Anyone else having issues with Web Gallery?
I don't believe Microsoft is going to remove the feed but wont update the products any longer. We have submitted a bug to WordPress which has been set to be included in WordPress 5.9 release and should allow us to include the latest version.
Would you be able to include your custom feed and we can see if its possible to replicate the issue? I know some domains are set as fully trusted so this could be the cause.
