Looks like my situation is resolved. I tried creating a new scheduling Lindy and received the same error, but when I gave the Lindy a new name (changed the default Lindy Name) it allowed me to save my work and move forward.

Found in the documentation that Pro is supported. I deleted this test, logged out/in, then added a new "inbound" to test. It showed my available voice number to use but when I selected it, I received an "invalid form submission" error. The Lindy still created but it is in the same state and will not let me save or modify still getting the same error as shown in the image above.
