I'm global admin on a Tenant and I have the Sites Web Part added to my Root level communication Site. I want to add ALL sites on the tenant to this web part but it'll only let me add those I'm a member of. I don't think I should have to be a member of 100+ sites in order to add them to a web part so, is there a way around this please?
Unfortunately Sites WebPart does not support the scenario you describe...it relies on search to: a) Dnamically add the sites you are memvber off b) Dynamically add the sites that belong to a Hub Site c) Manually add sites that belong to a Hub Site or you are member off
Not to mention I’m pretty sure this is a personalized webpart. Meaning whatever you add is for your eyes only not everyone else to see. So even if you had access and added them all no one else would see them.
