Help: Update my app?

Hi, I published this app (version 1.0):

Then I corrected a bug and updated the repository on GitHub (version 1.1):

Then, by mistake, I wanted to make a new merge request to publish the update:
but they told me that was not necessary, but do I have to do something to publish the update?

There is no new version


OK thanks

Is it necessary to re-tag?

EDIT: Ok, re-tagging done!

Yup, delete Tag, retag with the new commit

Done! Our comments were crossed.
Thank you very much!
