Can't see Copilot icon anymore!

One possible reason is your group polices disabling the sidebar and apps, check this if it helps:

But I guess it's most likely a region block thing. I'm in mainland China. I noticed it'd show if you installed a new/beta version but then it'd disappear.
I tried to proxy all my network traffic thru the VPN to Los Angeles. I changed the region, ,time zone , language in the Windows 10 settings but it didn't work either.
Somehow both Bing and Google still managed to locate my IP in China( those "where's my ip" webs can be easily fooled tho) , even if I started a clean guest profile.
It's probably the ISP giving away my real IP. Or my VPN just didn't work like I expected.
But, think about it, missing icon means we can't use Bing summarizer for webpages and PDFs. We can still use it in the official chat page.
So maybe we could move on, use some GPT based extensions for that purpose.
