Where have the pen icon in Microsoft Edge gone?

Sure you are using Edge Dev/Canary browser? This would not be available in stable.

@all those who are complaining that no, this isn't good, I am just a volunteer/MVP having no connection with MS. Feel free to send feedback to MS using Alt+Shift+I buttons.

I used "windows ink workspace button"/ "Snip and Sketch".  I right clicked on the taskbar, then checked off "Show windows ink workspace button".  Hope this helps some.

I wish they kept the pen too, but also understand that, for the majority of users, the pen wasn't the main selling point for them. The other improvements the Chromium update brought (updated UI, greater extension support, faster browsing, etc) probably mattered more.

exactly,

this has gone on too long and needs to be rectified. The pen is crucial to future of laptops and to forget  or not address this issue is ludicrous.

Microsoft needs to publicly address this situation to us, tell us what is the plan so we can expect the functionality that we paid for when we bought machines and pens for specific purposes. To eliminate a function that was the basis of a sale is actually criminal.

It is time to get it right.

The pen is the only reason I bought a Surface. Not happy. Last Surface I buy.
