[Solved] "Add Quote Tax" Submit Button Not Functioning

I am trying to add a quote tax to a newly created quote but the “Submit” button isnt working. However if I create an Invoice, I am able to add an Invoice Tax.

Can confirm this.
Could you add this to the repo as a bug report?

Will go ahead and do that.

Has there been any fix to this issue?

Has been fixed and will be included in the next version v1.1.0 coming at the end of october.
