I have looked at your Micropub plugin and then debugged the issues with claude and I think I found the problem, nothing to do on your side, it was really a bug on my side : https://github.com/rmdes/plume/releases I submitted version 1.3.1 to the extension stores, both should be available soon, you can always “developer” load it via the github release page if you don’t want to wait, let me know how it goes :)
