I am trying to publish an update to my visual studio extension. I have followed the steps in https://docs.microsoft.com/en-us/visualstudio/extensibility/how-to-update-a-visual-studio-extension , however, when I try to upload my updated VSIX file (by pressing 'New Extension' and selecting the VSIX file), I get the following error:
The VSIX ID in the provided file is already in use. Every extension needs to have an unique ID. Provide a file with an unique ID.
How do I publish this update? I don't see an update button anywhere...
