Hello, PCL_253
Welcome to Microsoft Community.
It seems like you’re experiencing an issue with sharing a Microsoft Loop page. As of my last update, to share a Loop page as a component, you would typically click on the name of the page and then select the appropriate sharing options. That is to say, the process hasn't been changed yet. However, if nothing happens when you click, try using a different browser or an incognito/private window to see if the issue persists. Sometimes, browser extensions or settings can interfere with the functionality of web applications.
Also, try another device or network, as there might be a temporary glitch with the network connection.
If the problem continues, providing feedback may help address this if it’s a bug or a feature change. Click on ··· > Help & feedback on the upper right corner.
