The release notes indicate that the base code version after installing this tax engine should be 1.1.0.0. The last tax engine set that was released (2020-R1 and 2020-R1d) put us at base code version 1.0.3.0. 2020-R1 included an application hotfix and a kernel hotfix.
I think we need an application hotfix to get us up to base code version 1.1.0.0.
Thanks.
